| 摘 要： | 重新界定的夹皮沟金矿集中区包括了太古宙花岗-绿岩带和高级变质区两个组成部分。这-太古宙地体除受到新太古宙-早元古宙的金矿成矿作用外，还受到中生代构造岩浆活动的影响，使该区金矿具有多期成矿特点。有利构造部位上的地球化学异常是寻找金矿的切入点，经查证，在高级变质区内发现了大型构造蚀变岩型六批叶沟金矿。强调了在成矿集中区内找矿的重要性。

| Abstract: | The redelimited Jiapigou gold-concentrated area is composed of Archean granitoid-greenstone belts and high grade metamorphisic areas. Besides the gold metallogenesis from the Neoarchean epoch to the Paleoproterzoic epoch, the Archean terrain of the area was influenced by mesozoic tectonomagmatic activity, resulting in the characteristic of multi-epoch metallization of gold in the area. Geochemical anomalies in favorable structures,which are keys to the gold deposit prospecting, were detected, and a tectonic-altered rock type gold deposits have been found in the high grade metamorphisic areas. The importance of prospecting within the ore-concentrated areas is emphasized in the thesis. |
