| 摘 要： | 论述了农坪金矿带成矿地质条件，认为下古生代志留纪下统五道沟群杨金沟组变质岩，中生代三迭纪安山凝灰角砾岩，燕山期岩浆岩（闪长岩，英云闪长（斑）岩，闪长玢岩，花岗斑岩）为金的成矿主要源体；分析了农坪金矿床的成因机制，确定为次火山热液蚀变岩型金矿床；指出应在火山口及周边部的火山－次火山岩中寻找金矿床。

| Abstract: | The mineral-formation condition of the Nongping Au metallogenic zoning is discussed in this paper. It is considered that metamorphic rock of Yangjingou Formation, Wudaogou Group, Lower Silurian, lower Paleozoic, Yanshan magmatic rock(diorite, tonalite, tonalite-porphyry, diorite-porphyrite and granite-porphyry) are major Au metalogenic bodies; through the analysis on the genetic mechanism of the Nongping Au deposit, it is determined that it belongs to subvolcanic hydrothermal alteration Au deposit; pointing out that we should search for Au deposit in the crater or adjacent volcano-subvolcano. |
