无产阶级文化大革命以来,遵照伟大领袖毛主席关于“实践、认识、再实践、再认识”的教导,对南岭具有代表性的诸广山花岗岩体进行了较详细的研究,目的是了解本区岩浆活动的特点和岩体形成的某些物理-化学条件。所采取的主要手段是野外地质研究方法。在大量野外实际观察的基础上,我们采集了约70个新鲜而具代表性的大样及大量岩矿标本,从同位素地质学、岩石学、岩石化学方面进行了研究。对主要造岩矿物、副矿物,少量元素和锆、铪等都做了分析化验及矿物常数测定和数量统计。为避免取样的差异,各种分析测试尽量取自同一个大样,除少数同位素地质年龄外,所有数据均系本单位测试。岩体
Since the Great Proletarian Cultural Revolution, following the guidance of Chairman Mao on “practice, understanding, re-practice and re-understanding”, we have conducted a more detailed study of the various Guangshang granite bodies in Nanling in order to understand this area Characteristics of magmatism and some physico-chemical conditions of rock mass formation. The main method adopted is field geology research method. Based on a large number of field observations, we collected about 70 fresh and representative large samples and a large number of rock and mineral samples from isotope geology, petrology and rock chemistry. The main rock-forming minerals, minerals, minor elements and zirconium, hafnium and so have done analysis and determination of mineral constant and the number of statistics. In order to avoid sampling differences, all kinds of analytical tests are taken from the same large sample as much as possible. All the data are tested by this unit except for a few isotopic geological ages. Rock mass
