山东省莱州市三山岛金矿床地质特征及成因探讨

莱州—招远地区是我国最重要的金矿资源基地,截止目前已发现的各类金矿床（点）200余处,其中大、中型金矿床20余处,已探明的储量占全国的1/4.三山岛金矿床是区内著名的“焦家式”金矿的典型代表之一.文章通过对三山岛金矿床地质特征研究表明,矿体地质特征与控矿断裂构造特征相一致,矿床成因属于重熔岩浆期后中温热液交代矿床.

Geological characteristics of Sanshandao Island gold deposit in Laizhou, Shandong Province and the genetic discussion

Laizhou-Zhaoyuan area is the most important gold mineral resources base of China. So far more than 200 various gold deposits （occurrences） have been located. Gold reserves proven here is about a quarter of the total reserves of the whole China. Of the 200 about twenty are large, medium gold deposit.
