随着区域化探工作的开展,对区域化探数据如何整理,以提供更多、更有效的信息,是当前化探工作中应当重视的问题.我们应用多元统计方法,对广东西部区域化探所获的地层和岩体资料的整理、研究,作了一些尝试.本次工作范围,仅限于广东西部.构造部位属于东西向新华夏系第二隆起带的西南段.区内自元古界震旦系、到新生界第四系地层均有出露.我们选用了震旦系、寒武系、志留系、泥盆系、石炭系、二迭系和白垩系地层样品计441个,采用广东冶金地质九四○队所提供的分
With the development of regional geochemical exploration, how to organize regional geochemical data to provide more effective information is a problem that should be paid more attention to in the current geochemical exploration work.We applied multivariate statistical method to the regional geochemical exploration in western Guangdong The work area is limited to the western part of Guangdong.The structural parts belong to the southwestern section of the second uplift belt of the Xinhua-Hsi system in east-west direction, Sinian, to the Cenozoic Quaternary strata are exposed.We use the Sinian, Cambrian, Silurian, Devonian, Carboniferous, Permian and Cretaceous stratum 441, Adopted by the Guangdong metallurgy geological team provided ninety-four points
