Metallogenic Regularity and Prospecting Direction of Feldspar Deposit in Shandong Province
摘要
Abstract
Through analyzing spatial-temporal distribution, characteristics, formation conditions and the origin of feldspar deposits in Shandong province, the types of deposits have been classified and the metallogenic regularities have been summarized. The metallogenic material of feldspar comes from the magma containing SiO2, Al2O3, K2O and Na2O in the later stage of magma, and tectonic fissure is an important channel for the migration of metallogenic material. According to the symbiotic relationship and structural characteristics of granite pegmatite minerals, the feldspar granite pegmatite deposits are divided into two types: weak differentiation type and differential type. Feldspar deposits are mainly distributed in magmatic areas, closely related to magmatic activities. It mainly occurrs in pegmatite of various ages, and granite-pegmatite type feldspar deposits are its main type. In time distribution, feldspar deposits occur in all periods from Neoarchean to Mesozoic. According to metallogenic regularities, the prospecting direction of feldspar deposit has been pointed out.关键词
