地质学是关于固体地球组成、结构及地球演化历史的知识体系。现代地质学不仅要阐明固体地球的组成物质、控制物质转换的机制以及由这些物质记录的地球演化历史，而且要揭示改变固体地球外层的营力和改造地球表层的过程，并运用地质学知识探明可供利用的物质以及理解地质过程与人类活动相互作用的机理

一、用途 测定折射率、双折率、光性

金绿宝石(Chrysoberyl) 1、主要特征 成分:BeAl2O4 晶系:斜方,二轴晶,正光性(+)

钻石晶莹剔透、光芒四射并有 “钻石恒久逸一颗永流传”的赞誊, 这些都是由钻石的基本性质决定的

当光波从一种介质传到另 种介质时,其传播速度和方 向会发生改变这种现象叫折 射。光在入射介质中的传播 速度与折射介质中的传播速 度之比,等于入射角正弦与 折射角正弦之比

What is Metamorphism?1) Metamorphism is the change in form that happens in Earths crustal rocks in response to changes in temperature and pressure

Introduction: Sediments In The Rock Cycle Sediments are transported by: Water. ce Wind. Gravity. The transport and deposition of sediments are initial phases of the rock cycle. The ultimate fate of most sediment is burial and conversion to sedimentary rock

Introduction: Weathering The Breakdown of Rock At the Earth's surface, rocks are exposed to the effects of weathering: the chemical alteration and mechanical breakdown of rock, when exposed to air, moisture, and organic matter. Weathering is an integral part of the rock cycle. Weathering converts rock to regolith
