研究火成岩对找矿有极大的实际意义,特别是寻找有色金屬、黑色金屬以及稀有金屬。这些金屬矿床和火成岩有一定的共生規律,如鎢、錫、钼、铜、鉛等矿产和酸性或中性火成岩有关,鉻、鑠、鉑等矿产和超基性火成岩有关。研究火成岩的侵入时代也有很大意义,因为大多数的有色金属和稀有金屬矿床,和年青的浸入体关系比较密切。在这里研究的个是火成岩和矿床的关系,而是怎样来判断火成岩的先后生成次序。这样虽然不是直接研究火成岩的侵入时代,但将区域內所有的火成岩生成順序研究清楚,也就间接地帮助。判断火成岩的侵入时代,然后再深入一步研究火成岩和矿床的关
Studying igneous rocks has great practical significance for prospecting, especially looking for non-ferrous metals, ferrous metals and rare metals. These metallogenic deposits and igneous rocks have some symbiosis rules. Some minerals such as tungsten, tin, molybdenum, copper and lead are related to acidic or neutral igneous rocks, and the minerals such as chromium, molybdenum and platinum are related to ultrabasic igneous rocks. It is also of great significance to study the age of igneous intrusion, as most of the nonferrous metals and rare metal deposits are closely related to young dipping bodies. The one studied here is the relationship between igneous and mineral deposits, but how to determine the order of occurrence of igneous rocks. Although this is not a direct study of the invasive age of igneous rocks, all the igneous rocks in the region have been studied in a clear and indirect way. Judge the age of igneous invasion, and then further study igneous rock and deposit off
