什么是“鲍文反应系列”（Bowen's reaction series）？它说明了什么？
What is Bowen's reaction series, and what does it explain?
鲍文反应系列由诺曼·鲍文在1920年代通过实验总结：岩浆冷却时矿物按一定顺序结晶——不连续系列为橄榄石→辉石→角闪石→黑云母，连续系列为斜长石成分由钙长石渐变为钠长石。它解释了火成岩矿物组合的规律及分异结晶现象。
Bowen's reaction series, formulated by Norman Bowen in the 1920s from experiments, shows the order in which minerals crystallize as magma cools: a discontinuous branch (olivine → pyroxene → amphibole → biotite) and a continuous branch (plagioclase shifting from calcium-rich to sodium-rich). It explains the mineral assemblages of igneous rocks and fractional crystallization.

鲍文反应系列揭示了岩浆结晶的什么规律？
What pattern of magma crystallization does Bowen's reaction series reveal?
鲍文反应系列把矿物按结晶温度从高到低的顺序排成两支：连续系列从钙长石到钠长石，不连续系列从橄榄石到石英。它说明岩浆冷却时矿物依次分离结晶，残余熔体成分随之演化。这一规律由鲍文在1928年《火成岩的演化》中系统提出，是火成岩分类的基础。
Bowen's reaction series arranges minerals by falling crystallization temperature into two branches: a continuous series from calcium-rich to sodium-rich plagioclase and a discontinuous series from olivine toward quartz. It shows that as magma cools, minerals crystallize and separate in sequence while the residual melt evolves in composition. Bowen set this out in 1928 in The Evolution of the Igneous Rocks, founding igneous petrology.

解理和断口有什么不同？
What is the difference between cleavage and fracture?
解理是矿物沿特定薄弱方向规则裂开成平滑平面的性质，断口则是矿物不按规律破裂形成的不规则表面。云母易沿一层层解理剥开，而石英常呈贝壳状断口。
Cleavage is a mineral's tendency to split along preferred weak directions into smooth planes; fracture is its irregular breakage when no cleavage direction is followed. Mica cleaves into sheets, while quartz typically shows a conchoidal fracture.

什么是“岩石循环”？它描述了哪些过程？
What is the 'rock cycle,' and what processes does it describe?
岩石循环描述岩石在地球内部与外部之间不断转化的过程：岩浆冷却成火成岩，火成岩经风化侵蚀变为碎屑并沉积成沉积岩，二者在高温高压下变质为变质岩，变质岩再熔融回到岩浆。它把板块运动、风化和火山等过程连成一体。
The rock cycle describes how rocks are continually transformed between Earth's interior and surface: magma cools to igneous rock, which weathers and erodes into sediments that form sedimentary rock, and both can be metamorphosed under heat and pressure, then melted back to magma. It links plate tectonics, weathering, and volcanism into one system.

侵入型火成岩和喷出型火成岩有何区别？
How do intrusive and extrusive igneous rocks differ?
岩浆在地下缓慢冷却形成颗粒较粗的侵入型（深成）火成岩如花岗岩；喷出地表快速冷却则形成颗粒细甚至玻璃质的喷出型（火山）火成岩如玄武岩。冷却速度决定了晶体大小。
Magma that cools slowly underground forms coarse-grained intrusive (plutonic) rocks like granite; lava that cools quickly at the surface forms fine-grained or glassy extrusive (volcanic) rocks like basalt. Cooling rate sets crystal size.

硅酸盐四面体为何是地壳大多数矿物的基本构造单元？
Why is the silicate tetrahedron the basic building block of most crustal minerals?
硅酸盐四面体由一个硅原子居中、四个氧原子居角构成，是地球富硅富氧成分下最稳定的结构单元。它们通过共享氧原子连接成岛状、链状、片状或架状，形成从橄榄石到长石再到云母的多样矿物。克莱因与赫尔伯特的《矿物学手册》详细列出了这些聚合方式。
The silicate tetrahedron, a silicon atom at the center and four oxygens at the corners, is the most stable unit given Earth's silicon- and oxygen-rich composition. By sharing oxygens they link into isolated, chain, sheet, or framework structures, yielding diverse minerals from olivine to feldspar to mica. Klein and Hurlbut's Manual of Mineralogy details these polymerization styles.

变质作用在什么温压条件下改变岩石，有哪些主要类型？
Under what temperature and pressure conditions does metamorphism alter rocks, and what are its main types?
变质作用指固态岩石在升温、增压或流体的作用下矿物重排而不熔融，通常发生于地下十几到数十公里。接触变质由岩浆热力主导，区域变质则与造山带的深埋和定向压力相关。布赫与弗雷在《变质岩岩石成因》中系统梳理了对应的矿物组合。
Metamorphism rearranges a rock's minerals in the solid state under heating, pressure, or fluid action without melting, typically tens of kilometers underground. Contact metamorphism is driven by magmatic heat, while regional metamorphism accompanies deep burial and directed pressure in mountain belts. Bucher and Frey's Petrogenesis of Metamorphic Rocks catalogs the corresponding mineral assemblages.

什么是莫氏硬度计？
What is the Mohs hardness scale?
莫氏硬度计用1到10的等级表示矿物相互刻划的相对硬度，滑石最软为1，金刚石最硬为10。它便于野外粗略鉴别矿物，但不是线性的绝对硬度。
The Mohs scale ranks minerals from 1 to 10 by their relative resistance to scratching, with talc softest at 1 and diamond hardest at 10. It helps rough field identification but is not a linear measure of absolute hardness.

矿物是如何被定义的？常用的“莫氏硬度计”是什么？
How is a mineral defined, and what is the Mohs hardness scale?
矿物须同时满足：天然形成、无机、固态、有确定的化学成分、内部原子呈有序晶体排列。莫氏硬度计由弗里德里希·莫斯于1812年提出，用1（滑石）到10（金刚石）的十种标准矿物表征相对划痕硬度，数值越大越难被划伤。
A mineral must be naturally occurring, inorganic, solid, with a definite chemical composition and an ordered crystalline atomic structure. The Mohs hardness scale, proposed by Friedrich Mohs in 1812, ranks relative scratch hardness from 1 (talc) to 10 (diamond), where a higher number scratches a lower one.

长石为什么重要？
Why is feldspar important?
长石是地壳中含量最丰富的矿物族，占地壳矿物总量约六成，常见于花岗岩等岩石中。它风化后形成黏土和土壤的关键成分，也是陶瓷和玻璃工业的重要原料。
Feldspar is the most abundant mineral group in the crust, making up roughly 60% of crustal minerals and common in rocks like granite. It weathers into clays and soil ingredients and is vital to ceramics and glass making.

岩石按成因主要分为哪三大类？
What are the three main rock types classified by origin?
岩石按成因分为火成岩（由岩浆冷却凝固形成，如花岗岩、玄武岩）、沉积岩（由碎屑或化学沉淀经压实胶结形成，如砂岩、石灰岩）和变质岩（原有岩石在高温高压下改变而成，如大理岩、片岩）。这三类通过“岩石循环”相互转化。
Rocks are classified by origin into igneous (formed by cooling of magma, e.g., granite, basalt), sedimentary (formed by compaction and cementation of fragments or chemical precipitates, e.g., sandstone, limestone), and metamorphic (altered from existing rock by heat and pressure, e.g., marble, schist). They transform into one another through the rock cycle.

花岗岩和玄武岩的主要区别是什么？
What are the main differences between granite and basalt?
花岗岩是浅色、富含石英和长石的深成岩，形成于地壳较厚的大陆环境，冷却缓慢故晶粒粗大。玄武岩是深色、贫硅富铁镁的喷出岩，多分布于洋壳，冷却快而常见细粒或玻璃质。两者成分与产出的差异反映了不同板块构造背景。
Granite is a light-colored, quartz- and feldspar-rich intrusive rock formed in thicker continental crust, cooling slowly so its grains are coarse. Basalt is a dark, silica-poor, iron- and magnesium-rich extrusive rock common in oceanic crust, cooling fast into fine-grained or glassy texture. Their compositional and tectonic differences reflect distinct settings.
