豫西地区18个中酸性岩体中的岩浆包裹体,分布于石英及长石中,形状多为圓形,大小2—110微米呈单体或群体存在于矿物中,按其性质可分为玻璃质熔融包裹体和结晶质包裹体两种,均一化温度在880—1072℃之间。岩浆包裹体是封存在矿物中的原始岩浆。它是研究成岩作用的样品。对提供岩体成因,硅酸盐熔体干、湿两类的划分,岩浆演化,岩浆起源深度与温度压力等信息,具有重要的地质意义。
The magmatic inclusions in 18 intermediate-acidic rocks in western Henan are distributed in quartz and feldspar. Most of them are round in shape. The size of 2-110 μm is single or group present in minerals, which can be divided into Glassy melt inclusions and crystalline inclusions two, the homogenization temperature between 880-1072 ℃. Magmatic inclusions are the original magma enclosed in minerals. It is a sample of diagenesis. It has important geological significance to provide information such as genesis of rock mass, classification of dry and wet silicate melt, magmatic evolution, depth of magma origin and temperature and pressure.
