| 摘 要： | :本文概述了老厂红土型银锰矿床成矿地质背景、地质特征及成矿规律,提出本矿床总体属初生红土型银锰矿床,成矿作用主要与红土化作用有关,银锰成矿物质主要来源于C2+3—P1碳酸盐岩,并将银锰次生富集过程划分为四个阶段。

GEOLOGY AND GENESIS OF THE LATERITIC TYPE Ag-Mn ORE DEPOSIT AT LAOCHANG IN LANCHANG AREA,YUNNAN PROVINCE |
| |
| Abstract: | The minerogenetic background,geological characteristics and metallo genic regularities of the Lao-chang lateritic Ag -Mn ore deposit are briefly introduced in this paper.T he deposit is classified as juvenile type lateritic Ag -Mn deposit,the mi neralization is chiefly related to l aterization,ore-forming elements are mainly derived from C 2+3-P 1 carbonate rocks.The process of secondary enrichment of silver and magnesium can be divided into four stages. |
