| 摘 要： | 在学习相关规范、规程的基础上,经过1∶5万漕涧幅地质调查实践,对花岗岩类岩石矿产地质调查的野外观察记录形成了一些初浅的认识与体会。其野外观察记录的要求和内容是对花岗岩的主要矿物与次要矿物进行野外鉴定、岩石结构与类型的初步划分、岩体侵入体的接触关系判断、包体类型及其特征等地质现象的描述和记录。认真做好花岗岩类岩石地质调查的野外观察记录,可较大幅度地提高花岗岩类区矿产地质调查质量。

| Abstract: | On the basis of a study of the relative rule,standard and according to the practice in geological survey of 1:50000 Caojian sheet,we have some preliminary knowledge and experience of field observation and record about granitoid geology and mineral resource survey,including the field determination of major and minor minerals,preliminary classification of rock structure and type,discrimination of rockbody contact relation,inclusion type and feature,etc.The careful field observation and record of granitoid can improve evidently the quality of geological and mineral resource survey of granitoid area. |
