墨西哥｜Mexico

墨西哥位於北美洲南部，西側面向太平洋，東側連接墨西哥灣與加勒比海。狹長而彎曲的國土，從北方乾燥高原與荒漠，延伸至中央火山山地、南部複雜山系，以及東南方低平的猶加敦半島。海洋、高原、山脈與熱帶低地彼此相接，使墨西哥無法由單一沙漠、火山或海岸概括。

墨西哥地表可分成多個具有不同地質與地形特徵的區域。國家地理資料將其劃分為西馬德雷山脈、東馬德雷山脈、中央高原、跨墨西哥火山帶、南馬德雷山脈、墨西哥灣沿岸平原及猶加敦半島等主要地形省。這些區域的差異來自岩石組成、地質構造、海拔、水系與長期侵蝕作用的共同影響。

北部與中北部的核心，是廣大的墨西哥高原。

高原大致位於西馬德雷山脈與東馬德雷山脈之間，內部分布山脊、盆地、乾燥平原與封閉低地。雖然地表常呈現開闊而平緩的樣貌，實際上仍被斷裂、局部山地與沉積盆地反覆切分。水分有限，使植被較為稀疏，岩體、礫石與風化表面也更容易直接顯露。

西馬德雷山脈沿墨西哥西側延伸，廣泛保存火山岩與被河流切開的高原地形。深谷、岩壁與層狀山體，使這片區域同時呈現火山堆積與後期侵蝕留下的結構。東馬德雷山脈則主要由受擠壓與褶皺影響的岩層構成，山脊與谷地大致沿國土東側延伸，並在部分地區形成高原與墨西哥灣低地之間的明顯界線。

橫越國土中部的跨墨西哥火山帶，則改變了山系原本偏向南北延伸的方向。

這條地形與火山帶大致由西向東展開，包含火山、高原、盆地與高海拔山地。火山活動、岩漿作用與地殼斷裂在不同時期留下熔岩、火山碎屑岩、火山錐與相關岩體，也使墨西哥中部成為地形高度集中、地質作用複雜的區域。墨西哥地質調查機構將其視為環太平洋火山與構造系統的一部分。

向南移動，地形再次分裂。

南馬德雷山脈、瓦哈卡山地與恰帕斯山系之間，分布深谷、盆地、沿海山地與狹窄平原。太平洋一側的山脈常靠近海岸，地勢在很短距離內迅速升高；墨西哥灣一側則展開較寬廣的低地與河流平原。高地與低地之間的落差，使溫度、降雨與植被在相對有限的距離內持續轉換。

東南方的猶加敦半島，呈現完全不同的地表。

這裡整體較為低平，以石灰岩地層為主。降雨容易沿裂隙進入地下，使地表河流相對有限，地下水、洞穴與天然井則成為重要的水文形式。與中央火山山地及北方裸露高原相比，猶加敦的地景更多由可溶岩層、地下空間與熱帶植被共同構成。

墨西哥內部的氣候差異，也受到緯度、海拔與山脈方向共同控制。

北部內陸普遍較為乾燥，中央高地因海拔而具有相對溫和的環境；南部與東南部則更接近濕潤熱帶。面向海洋的坡面能接收較多水氣，而位於山系背後的盆地與高原，則可能形成更加乾燥的環境。墨西哥因此同時包含荒漠、乾草原、溫帶高地、雲霧森林與熱帶低地。

這些地形建立在複雜而持續變動的地質背景之上。

板塊作用、火山活動、岩漿侵入、斷裂、熱液循環、沉積與變質作用，在不同地區形成各自的岩體與礦化環境。墨西哥地質調查資料以岩性、斷層、裂隙、礦床與熱液蝕變等資訊建立區域地質圖，也顯示墨西哥的礦物資源並非來自單一形成系統。

墨西哥長期以銀、金、銅、鉛、鋅及其他金屬礦產受到認識，也保存螢石、方解石、石英與多種收藏礦物。不同礦床可能形成於熱液脈、矽卡岩、火山岩、沉積岩或其他岩體之中，使晶體呈現截然不同的顏色、晶形、母岩與共生關係。墨西哥地質調查局所列的礦床資料，也顯示不同州與礦區具有彼此不同的成礦類型。

因此，「墨西哥礦物」並不存在一種能夠代表全部的外觀。

北方荒漠礦區、中央火山帶、古老金屬礦山、南部山地與墨西哥灣沿岸，可以產生完全不同的礦物組合。國家名稱提供的是廣大範圍；真正的風土，仍需要進一步走入州、礦區、村落與具體採集地點。

Mexico lies in the southern part of North America, facing the Pacific Ocean to the west and the Gulf of Mexico and Caribbean Sea to the east. Its long, curved territory extends from the arid plateaus and deserts of the north through central volcanic highlands and complex southern mountain systems to the low-lying Yucatán Peninsula in the southeast. Oceans, plateaus, mountains, and tropical lowlands meet within the same country, making it impossible to represent Mexico through a single desert, volcano, or coastline.

Mexico is divided into several physiographic regions with distinct geological and topographic characteristics. National geographical data identify provinces including the Sierra Madre Occidental, Sierra Madre Oriental, Mexican Plateau, Trans-Mexican Volcanic Belt, Sierra Madre del Sur, Gulf Coastal Plain, and Yucatán Peninsula. Their differences reflect rock composition, geological structure, elevation, drainage, and long-term erosion.

The broad Mexican Plateau forms the geographical core of the north and north-central regions.

It lies largely between the Sierra Madre Occidental and Sierra Madre Oriental and contains ridges, basins, arid plains, and enclosed depressions. Although much of the surface appears open and relatively level, it is repeatedly divided by faults, local mountain ranges, and sedimentary basins. Limited moisture leaves vegetation sparse in many areas, allowing rock, gravel, and weathered surfaces to remain directly visible.

The Sierra Madre Occidental extends along western Mexico and preserves extensive volcanic rocks and plateau terrain cut by rivers. Deep canyons, cliffs, and layered mountain forms reveal the combined effects of volcanic accumulation and later erosion. The Sierra Madre Oriental, in contrast, contains strongly folded and compressed rock layers. Its ridges and valleys extend along the eastern side of the country and form an important boundary between the interior plateau and the Gulf lowlands.

The Trans-Mexican Volcanic Belt crosses the center of the country and interrupts the predominantly north–south direction of the major mountain systems.

Extending broadly from west to east, it includes volcanoes, uplands, basins, and high mountain terrain. Volcanism, magmatism, and crustal fracturing produced lava, volcanic deposits, cones, and intrusive bodies at different times, making central Mexico a region of concentrated relief and complex geological activity. Mexico’s Geological Survey places this volcanism within the wider circum-Pacific tectonic system.

Farther south, the terrain divides again.

The Sierra Madre del Sur, the mountains of Oaxaca, and the ranges of Chiapas contain deep valleys, basins, coastal mountains, and narrow plains. Along the Pacific, mountains often rise close to the coast, producing rapid changes in elevation. Along the Gulf side, broader lowlands and river plains extend toward the sea. Temperature, rainfall, and vegetation can therefore change sharply over relatively short distances.

The Yucatán Peninsula presents a very different surface.

It is generally low and is dominated by limestone. Rainwater readily enters fractures in the soluble rock, leaving relatively few major surface rivers while creating extensive groundwater systems, caves, and cenotes. Unlike the volcanic highlands of central Mexico or the exposed plateaus of the north, Yucatán is shaped by soluble rock, underground space, and tropical vegetation.

Climate within Mexico is controlled by latitude, elevation, and the orientation of its mountain systems.

The northern interior is generally drier, while central highlands experience more moderate conditions because of elevation. Southern and southeastern regions are more strongly tropical and humid. Slopes facing the oceans receive moisture, while basins and plateaus behind mountain barriers may remain considerably drier. Mexico therefore contains desert, dry grassland, temperate upland, cloud forest, and tropical lowland environments.

These landscapes rest upon a complex and active geological foundation.

Plate interactions, volcanism, igneous intrusion, faulting, hydrothermal circulation, sedimentation, and metamorphism have created different rock bodies and mineralized environments throughout the country. Geological Survey mapping records lithology, faults, fractures, deposits, and hydrothermal alteration, demonstrating that Mexican minerals do not arise from a single geological system.

Mexico has long been recognized for silver, gold, copper, lead, zinc, and other metallic resources, as well as fluorite, calcite, quartz, and many collector minerals. Deposits may occur in hydrothermal veins, skarns, volcanic rocks, sedimentary rocks, and other geological settings, producing very different crystal forms, colors, host rocks, and mineral associations.

There is therefore no single appearance that can represent “minerals from Mexico.”

Northern desert districts, the central volcanic belt, historic metal mines, southern mountains, and Gulf regions can produce entirely different mineral assemblages. The country name establishes a broad range; terroir only becomes visible when the reading proceeds toward a state, district, village, and specific collecting site.

墨西哥位於北美板塊、太平洋板塊、科科斯板塊與加勒比板塊交互作用的區域。

持續的火山活動、岩漿侵入與熱液循環，形成大量礦脈與礦床，孕育出石英、方解石、螢石、黃鐵礦及多種共生礦物。

不同於巴西古老穩定的大陸地殼，也不同於安地斯山脈的持續造山，墨西哥展現的是火山帶持續塑造地景與礦物的力量。

Mexico lies at the intersection of the North American, Pacific, Cocos, and Caribbean plates.

Active volcanism, magmatic intrusion, and hydrothermal circulation have created abundant mineral deposits, producing quartz, calcite, fluorite, pyrite, and many associated minerals.

Unlike Brazil’s ancient continental crust or the actively rising Andes of South America, Mexico reflects the dynamic geological influence of volcanic mountain belts.

前面我們展示了墨西哥的風土與地質條件，接下來，讓我們從另一個角度閱讀這片土地。

墨西哥的土地橫跨乾燥高原、火山山脈與濕潤低地，地表長久經過火、抬升、侵蝕與水流的重新塑造。

對底域而言，墨西哥呈現的是「轉化」。

有些地方保存過去，是讓它維持原來的形態。

墨西哥則更像讓過去進入新的形式。

古代城市以金字塔、道路與方位，把日月、神祇與人的生活放入可以行走的秩序。後來，不同信仰在這片土地上相遇，原有的觀念沒有完全消失，而是在節日、儀式與日常生活中，獲得新的名稱與形體。

亡靈節便是最鮮明的意象。

在節日裡，死者並不只被留在遙遠的另一側。

花瓣、燭火、食物與祭壇為他們指出返回的道路，使思念從無形的感受，轉化成可以準備、觀看與共同經歷的相聚。這項傳統結合了前西班牙時期的信仰與天主教節期，也與玉米耕作週期的結束相連。

死亡沒有因此被否認。

它仍然帶著失去與距離。

但人透過儀式，讓缺席重新獲得位置，讓記憶不只停留在內心，也能進入家庭、食物、色彩與每年反覆抵達的時間。

轉化並不是抹去原來的事物。

而是讓已經發生的經過，找到另一種可以繼續存在的形式。

當視線進入墨西哥的礦物，這種轉化也以更直接的方式出現。

墨西哥礦物經常帶著強烈而清楚的色彩：金屬的明暗、黑曜石的深黑、釩鉛礦的橙黃與紅色，以及紫水晶在透明之中逐漸加深的紫。

色彩不是為物質遮上新的表面。

它是岩石、元素、溫度與流體經過漫長時間之後，留下的結果。

維拉克魯茲的紫水晶，便生長在火山安山岩的裂隙之中。部分晶體由無色透明逐漸轉為紫色，銳利的晶柱從乳白石英與深色岩體之間伸出。原本封閉於岩石中的空間，最後成為晶體生長與色彩出現的地方。

裂隙沒有只留下破壞。

它也提供了新的空間。

透明沒有始終維持無色。

它在生長之中接住紫色，使一件晶體同時保留原來的清透，以及後來逐漸形成的色彩。

墨西哥晶體帶來的觀看，因此不只關於完整與純淨。

它也讓人看見，一件物質如何經過火、壓力、斷裂與時間，最後形成比最初更鮮明的形態。

當這些礦物進入人的生活，它們所保存的也不只是產地與晶形。

那是一段變化已經發生的證據。

岩石曾經打開。

流體曾經進入。

元素與光線曾經在其中重新排列，最後使原本隱藏於地底的過程，以色彩與輪廓來到眼前。

墨西哥在底域之中，因此成為一種關於轉化的閱讀。

土地將火凝成岩石。

儀式將缺席轉化成相聚。

晶體則將黑暗中的變化，轉化成可以被觀看的色彩與形體。

轉化不是拋棄過去。

而是讓曾經經過的一切，不必停留在原來的位置，也能以另一種形式繼續存在。

願你在閱讀中，找到一種不必否認失去與改變，也能讓生命重新獲得形體的力量。

The preceding sections introduced the terroir and geological conditions of Mexico. Now, let us read this land from another perspective.

Mexico extends across dry plateaus, volcanic mountain systems, and humid lowlands. Its surface has long been reshaped by fire, uplift, erosion, and water.

For DIYU, Mexico presents itself through the idea of Transformation.

Some places preserve the past by keeping it close to its original form.

Mexico seems instead to allow the past to enter new forms.

Ancient cities arranged pyramids, roads, and directions into structures through which the sun, deities, and human life could be placed within a visible order. As different belief systems later met upon this land, earlier ideas did not disappear completely. They acquired new names and forms within festivals, rituals, and everyday life.

The Day of the Dead offers one of the clearest images of this process.

The deceased are not left entirely upon a distant shore.

Flowers, candles, food, and altars mark a path for their return, transforming remembrance from an invisible feeling into a reunion that can be prepared, seen, and shared. The tradition brings pre-Hispanic beliefs into relation with Catholic observances and also coincides with the completion of the annual maize cycle.

Death is not denied.

It continues to carry absence and distance.

Through ritual, however, absence is given a place again. Memory enters the home, food, colour, and a period of time that returns each year.

Transformation does not erase what came before.

It allows what has already occurred to discover another form through which it may continue.

When the gaze enters Mexico’s mineral world, this transformation becomes more immediate.

Mexican minerals often carry strong and distinct colours: the changing brightness of metal, the darkness of obsidian, the orange and red of wulfenite, and purple gradually deepening within transparent quartz.

Colour is not a new surface placed over matter.

It is what remains after rock, elements, heat, and fluids have acted over immense periods of time.

Amethyst from Las Vigas in Veracruz formed within fractures in volcanic andesite. Some crystals change from colourless transparency into purple, while sharp prisms rise between milky quartz and dark host rock. A space once enclosed within stone became a place in which crystal and colour could appear. This passage is based on the Las Vigas article in the uploaded DIGITAL Nov-Dec 2003 Mexico III Vol 34 no 6.2_減肥版(1).pdf.

The fracture did not leave only damage.

It also created space.

Transparency did not remain colourless.

Through growth, it received purple, allowing one crystal to preserve both its earlier clarity and the colour that formed later.

The experience of Mexican minerals is therefore not only about completeness or purity.

It also reveals how matter passes through fire, pressure, fracture, and time before arriving in a form more distinct than the one with which it began.

When these minerals enter human life, they preserve more than locality and crystal structure.

They preserve evidence that transformation has occurred.

Rock once opened.

Fluids entered.

Elements and light were rearranged within it, until a process hidden underground arrived before us as colour and form.

Within DIYU, Mexico therefore becomes a reading of transformation.

The land transforms fire into rock.

Ritual transforms absence into reunion.

Crystal transforms changes formed in darkness into colour and shape that can be seen.

Transformation is not the abandonment of the past.

It allows everything that has been endured to move beyond its original place and continue in another form.

May you find, through this reading, a strength that does not deny loss or change, yet still allows life to take form again.
