摘要
丰宁大营子一带大面积出露古元古代闪长岩和海西期二长花岗岩。两期侵入体的接触带附近金矿(化)点发育,并呈北东向带状集中分布于海西期侵入体的外接触带内。本区矿源、热源、水源都很丰富,成矿地质条件优越,具成矿远景,矿床成因与成矿规律符合“三源”成矿模式。
Many Paleoproterozoic diorite intrusions and the Hercynian monzonite granite intrusions were encircled in the region of Dayingzi-Fengning. It is in the contact zone of the two stage intrusions that lots of gold deposits, which concentratedly distributed in the exocontact zone of Hercynian intrusion with trend of east-north, have being found in this area. Because of its abundant sources of ore, heat and water, it is a superior area for gold mineralization. The genesis of deposits and the laws of metallization can be illustrated with ' three-source ore-forming theory'.
