贵州晚新生代矿产资源成因类型和成矿规律

本文将贵州晚新生代矿产资源分为沉积矿床和层控矿床二大成因类型。重点对层控矿床作了阐述,根据改造成矿作用程度和表生氧化成矿特点,进一步分为沉积——改造矿床、沉积——表生氧化矿床和沉积——改造——表生氧化矿床三类及若干亚类。并从成矿物质、成矿空间和成矿时间三个方面,对贵州晚新生代成矿规律作了探讨。其中,构造变异带成矿的规律至关重要。据此,对贵州晚新生代成矿区域作了划分;为成矿预测指明了方向。

Genetic Types And Mineralization Law Of Minerals Resources Of Late Cenozoic In Guizhou

This paper divides the known deposits of Late Cenozoic in Guizhou into sedimentary deposits and stratabound deposits, with the latter emphatically expounded. According to the reformation mineralization degrees and surface oxidation mineralization characters, the paper further divides the deposits of Late Cenozoic into sedimentary-Surface oxidized deposits, sedimentary-reformation deposits and sedimentary reformationsurface oxidized deposits. In addition, the minerogenic law of the deposits of Late Cenozoic in Guizhou is discussed from the three aspects of mineralization materials, space and time,among which the law of tectonic variation zone mineralization is the most important. According to these, the minerogenic regions and minerogenic times in Late Cenozoic in Guizhou have been classified, showing a direction for mineralization pediction.
