導言|Introduction

巴西位於南美洲東部,東側面向大西洋,國土橫跨赤道以南的廣大範圍。它幾乎占據南美洲東半部,從北方的亞馬遜河流域,延伸至中央高原、東部沿海山地、南部高原與廣闊海岸。如此巨大的尺度,使巴西不可能由單一森林、河流或氣候概括。

巴西的地表主要由高原、平原與低地凹陷共同構成。中央高原、米納斯吉拉斯中南部高地、東部亞馬遜高原與巴拉那高原,分布在不同區域;亞馬遜低地、潘塔納爾濕地與沿海平原,則呈現河流沉積、水分匯聚與季節淹水形成的另一種地貌。

北方的亞馬遜流域,是巴西範圍最廣大的地景系統之一。

無數河流從安地斯山麓、古老高地與森林內部匯入亞馬遜河。水在這裡搬運泥沙、切割河岸,也在低平土地上形成洪氾平原、支流與濕地。茂密森林覆蓋了大部分地表,使岩石不一定直接出現在視野之中,但在植物、土壤與河流之下,仍存在沉積盆地與古老結晶岩區域的差異。巴西官方地理研究也強調,亞馬遜內部並不是均質的森林,而包含不同地形、土壤與植被組合。

向中央移動,土地逐漸進入廣大的高原與草原環境。

巴西中央高原並不是單一平坦表面,而由台地、丘陵、河谷、山脊與低地凹陷共同構成。這裡也是多條大型河流系統的分水區。河流從較高地勢向不同方向流動,連接亞馬遜、托坎廷斯、聖弗朗西斯科、巴拉那與巴拉圭等流域,使中央土地成為水流向外展開的重要起點。

巴西東部與東南部的地形更加起伏。

沿著大西洋一側,古老高原與沿海山系接近海岸,形成丘陵、山脊、深谷與狹窄沿海平原。水分從海洋進入,受到地勢抬升後形成較高降雨,也使森林、裸露岩體與人類聚落密集交錯。巴西許多人口與城市長期集中在大西洋沿岸及其附近,土地的自然形態也因此與道路、農業、採礦和都市發展持續重疊。

東南內陸的米納斯吉拉斯,則呈現另一種高原世界。

丘陵、山地、河谷與古老岩體在這裡反覆交錯。「Minas Gerais」的名稱本身便與礦山和礦產歷史相連。鐵、金與其他工業礦產長期影響地方經濟,而東部與東北部的偉晶岩區,也以石英、綠柱石、海藍寶、電氣石、長石、雲母及多種收藏礦物聞名。巴西地質調查資料顯示,米納斯吉拉斯部分偉晶岩體可以同時產出海藍寶、藍綠色電氣石、石英、長石、雲母與其他稀有元素礦物。

向南進入巴拉那高原,地表又留下大規模火山活動的痕跡。

層層玄武岩覆蓋廣大區域,河流切開岩層後形成階地、峽谷與岩壁。火山岩中的孔洞與裂隙,後來可以被石英、玉髓、瑪瑙與紫水晶等礦物填充,使南部巴西形成與米納斯吉拉斯偉晶岩完全不同的晶體世界。

東北部與內陸乾燥區域,也不能被濕潤熱帶的印象遮蔽。

半乾旱高地、裸露岩體、低矮植被與季節性河流,使水分成為限制地景的重要條件。岩石在強烈日照、溫差與有限降雨之間持續風化,呈現與亞馬遜森林、東南山地及南部高原截然不同的表面。

因此,「巴西礦物」不存在一種可以代表全部的外觀。

晶體可能來自古老結晶岩中的偉晶岩,也可能形成於金屬礦脈、變質岩帶、火山岩孔洞或沉積環境。石英、紫水晶、綠柱石、電氣石、黃玉與其他礦物,會因產區、母岩與形成條件不同,呈現完全不同的晶形、色彩、包裹體與共生關係。

巴西首先提供的是一個近似大陸的國家範圍。

真正的礦物風土,需要繼續走進米納斯吉拉斯、巴伊亞、戈亞斯、南里奧格蘭德,以及更具體的礦區、山地與採集場所,才能逐漸被辨認。

Brazil lies in eastern South America, facing the Atlantic Ocean and extending across an immense area south of the Equator. It occupies much of the eastern half of the continent, reaching from the Amazon Basin in the north to the central plateaus, eastern coastal mountains, southern highlands, and a long Atlantic coast. At this scale, Brazil cannot be represented by a single forest, river, or climate.

Its surface is formed principally by plateaus, plains, and depressions. The Central Brazilian Plateau, the highlands of south-central Minas Gerais, the Eastern Amazonian Plateau, and the plateaus of the Paraná Basin occupy different regions. The Amazon lowlands, the Pantanal, and coastal plains present another type of terrain shaped by river deposition, converging water, and seasonal flooding.

The Amazon Basin in the north forms one of Brazil’s largest landscape systems.

Countless rivers descend from the foothills of the Andes, ancient uplands, and the interior of the forest before joining the Amazon River. Water transports sediment, reshapes riverbanks, and forms floodplains, tributaries, and wetlands across lower ground. Dense forest conceals much of the surface, yet beneath the vegetation and soil lie important differences between sedimentary basins and ancient crystalline regions. Brazilian geographical research also emphasizes that the Amazon is not a homogeneous forest, but contains many distinct combinations of relief, soil, and vegetation.

Toward the center, the land gradually enters broad plateaus and savanna environments.

The Central Plateau is not one continuous flat surface. It is composed of tablelands, hills, valleys, ridges, and depressions. It also functions as an important divide between major river systems. Water flows outward toward the Amazon, Tocantins, São Francisco, Paraná, and Paraguay basins, making central Brazil a region from which movement begins in several directions.

The landscape becomes more strongly divided in the east and southeast.

Along the Atlantic side, ancient plateaus and coastal mountain systems approach the ocean, creating ridges, hills, deep valleys, and narrow coastal plains. Moisture arriving from the sea is lifted by the terrain, while forest, exposed rock, and dense human settlement overlap. Much of Brazil’s population and urban development has historically concentrated near the Atlantic coast, where natural terrain has continually interacted with roads, agriculture, mining, and cities.

In the southeastern interior, Minas Gerais presents another highland world.

Hills, mountain ranges, valleys, and ancient rock bodies repeatedly intersect. The name “Minas Gerais” itself is connected with a long history of mines and mineral extraction. Iron, gold, and other industrial minerals have shaped the region, while pegmatite districts in the east and northeast are known for quartz, beryl, aquamarine, tourmaline, feldspar, mica, and many collector minerals. Geological Survey of Brazil records show that some pegmatites in Minas Gerais contain aquamarine, blue and green tourmaline, quartz, feldspar, mica, and rare-element minerals within the same regional systems.

Farther south, the Paraná Plateau preserves evidence of immense volcanic activity.

Successive basalt flows covered a vast region. Rivers later cut through these layers to form cliffs, steps, and gorges. Cavities and fractures in the volcanic rock were later filled by quartz, chalcedony, agate, and amethyst, creating a mineral world very different from the pegmatites of Minas Gerais.

The northeast and the drier interior should not be concealed beneath Brazil’s humid tropical image.

Semi-arid uplands, exposed rock, low vegetation, and seasonal rivers make water a defining limitation of the landscape. Strong sunlight, temperature change, and irregular rainfall continually weather the surface, producing conditions unlike those of the Amazon forest, southeastern mountains, or southern volcanic plateau.

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

Crystals may come from pegmatites within ancient crystalline rocks, metallic veins, metamorphic belts, volcanic cavities, or sedimentary environments. Quartz, amethyst, beryl, tourmaline, topaz, and other minerals take on different forms, colors, inclusions, and associations according to locality, host rock, and conditions of formation.

Brazil first provides a national range approaching the scale of a continent.

Its mineral terroir only becomes clearer when the reading enters Minas Gerais, Bahia, Goiás, Rio Grande do Sul, and eventually particular mountains, mines, and collecting sites.

地質背景|Geological Background

巴西位於南美洲東部,大部分地區建立於極為古老的克拉通之上,其地質歷史可追溯至數十億年前。

長時間的地殼穩定、岩漿活動、變質作用與熱液循環,共同形成大量石英脈與各類礦床,也孕育出世界著名的水晶、紫水晶、黃水晶、電氣石與綠柱石等礦物。

這些古老地質條件,使巴西成為世界上最重要的晶體形成區域之一。

Much of Brazil is built upon ancient cratons whose geological history extends back billions of years.

Long periods of tectonic stability, magmatic activity, metamorphism, and hydrothermal circulation created extensive quartz veins and a remarkable variety of mineral deposits.

These ancient geological foundations have made Brazil one of the world’s greatest crystal-forming regions.

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

河流、森林、高原、濕地與海岸分布在廣大的國土之中,水與季節持續改變地表,也使生命在濕潤與乾燥之間反覆移動。

對底域而言,巴西呈現的是「活力」。

活力不只是熱鬧、明亮或向外擴張。

它更接近一種持續回應的能力。

河流改變邊界,植物重新覆蓋土地,生命在環境變動之後,再次找到可以生長的位置。

因此,活力並不是從未經過消耗。

而是在消耗之後,仍能重新建立流動。

巴西的人文也在長久的相遇中形成。

不同族群、文化與歷史經驗,進入語言、飲食、信仰、城市與日常生活。它們沒有完全融合成單一面貌,卻在共同生活之中,不斷改變彼此的表達方式。

情感透過聲音、身體與群體進入空間。

個人的動作被另一個人接住,分散的聲音找到共同的節奏。即使壓力、衝突與不確定仍然存在,生活也能在回應之中繼續向前。

當視線進入巴西的礦物,活力則呈現為另一種物質印象。

體量、透明與色彩,使晶體即使保持靜止,觀看仍然不斷移動。

光線穿過晶面與裂隙,被色彩截住,又沿著不同方向重新展開。晶體沒有移動,內部的層次卻隨著角度與光線持續改變。

這些礦物不必被轉換成其他象徵。

它們只是以重量、透明、色彩與輪廓,在空間中清楚出現。

收藏也因此不是保存一個固定不變的畫面。

晶體的生長已經停止,觀看卻仍然繼續。早晨、午後與夜晚的光線,使同一件標本反覆呈現不同的表情,也讓物質在日常生活裡保持流動。

巴西在底域之中,因此成為一種關於活力的閱讀。

土地使水與生命持續改變。

人使情感與經驗進入共同生活。

礦物則讓重量、光線與色彩,在靜止之中保持變化。

活力不是否認疲憊與陰影。

而是在世界不斷改變時,仍然能夠作出回應,重新找到節奏,並以自己的形態,再次進入生活。

願你在閱讀巴西時,找到一種即使經過消耗,仍能讓感受、色彩與生活重新流動的力量。

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

Rivers, forests, plateaus, wetlands, and coastlines extend across its immense territory. Water and seasonal change continually reshape the surface, while life moves between moisture and drought.

For DIYU, Brazil presents itself through the idea of Vitality.

Vitality is not simply excitement, brightness, or outward expansion.

It is closer to the ability to keep responding.

Rivers alter their boundaries. Plants return to the land. After conditions change, life finds another place in which to grow.

Vitality does not mean remaining untouched by exhaustion.

It is the ability to restore movement after exhaustion has occurred.

Brazil’s human world was also formed through long encounters.

Different peoples, cultures, and historical experiences entered language, food, belief, cities, and daily life. They did not dissolve into a single identity, yet through shared life they continually reshaped one another’s forms of expression.

Feeling enters space through sound, the body, and collective presence.

One person’s movement is received by another, while separate voices find a shared rhythm. Even when pressure, conflict, and uncertainty remain, life continues through response.

When the gaze enters Brazil’s mineral world, vitality becomes another kind of material impression.

Scale, transparency, and colour allow observation to remain in motion even while the crystal itself is still.

Light passes through faces and fractures, is interrupted by colour, and opens again in another direction. The specimen does not move, yet its internal layers continue to change with angle and light.

These minerals do not need to become symbols of another world.

Through weight, transparency, colour, and outline, they simply establish a clear presence within space.

Collecting, therefore, is not the preservation of a fixed image.

The crystal has stopped growing, but observation continues. Morning, afternoon, and evening light repeatedly reveal different aspects of the same specimen, allowing matter to remain active within everyday life.

Within DIYU, Brazil therefore becomes a reading of vitality.

The land keeps water and life in transformation.

People allow feeling and experience to enter shared life.

Minerals allow weight, light, and colour to remain in motion within stillness.

Vitality does not deny exhaustion or shadow.

It is the ability to respond while the world continues to change, to recover rhythm, and to enter life again through one’s own form.

May this reading of Brazil help you find a force that allows feeling, colour, and life to move again, even after exhaustion.
