摘要
主体与岩浆成矿热液有关的、产于矿脉中的金矿体，称脉型金矿。本文以成矿深度作为脉型金矿的分类依据，胶东地区可分为中深和浅成两类脉型金矿。从成矿深度模型中，获得中深脉型金矿成矿深度的理论值主要为２．４６～３．８ｋｍ，浅成的为０．２２～２．４９ｋｍ。从矿体延深模型中，获得中深脉型金矿的延深理论值主要为０．４０２～１．００２ｋｍ，浅成的为０．１６４～０．５５８ｋｍ。论述了成矿深度与矿体延深模型的理论值为正相关，说明成矿深度的研究有重要意义。
Lode An refers to the orebodies came chiefly from magmatic hydrothermal ore--formingsolution,located in ore veins. Mineralization depth is one classifying basis of lode An, according to thatthere are two types of gold deposits--mesothermal and epithermal lode An. From the model of mineralization depth, theoretical mineralization depth of the two types can be got, from 2. 46 to 3. 8 km inmesothermal lode An and from 0. 22 to 2. 49 km in epithermal one. From the model of verticle range,theoretical extending in diping can also be calculated , from 0. 402 to 1. 002 km in mesothermal lode An and from 0. 164 to 0. 558 km in epithermal one. Correlation between mineralization depth and vertical range is also discussed in this paper, the present study shows that they are in positive correlation.
