地洼型堆积锰矿是目前锰矿的一种重要类型。具规模大、矿质好、围岩松、埋藏浅、易勘便采的特点。矿体呈似层状及不规则状等,分布在地洼区第四纪坡积物中。矿床的展布受地洼断褶构造控制。矿床的形成系含锰层经地洼期表生成矿作用改造,锰质淋积富化,再受破碎、搬运、堆积而成。因此,与矿源层及其风化富集的锰帽型和淋滤型矿床,形成了一套在时间上有先后相续的序列、空间上有彼此相关的布局、生因上互为因果。但又各有其特色的矿床组合。对预测找矿提供了新的依据。
Di depression-type accumulation of manganese ore is an important type of manganese. A large-scale, good minerals, rock loose, buried shallow, easy exploration and mining features. The orebodies are stratified and irregular, distributed in the Quaternary sediments in Diwa area. The distribution of the deposit is controlled by the geostrophic fold structure. The formation of the deposit is that the manganese-bearing layer is transformed by the mineralization of the depressions on the diagenesis stage, and the manganese-based deposition is enriched and then broken, transported and piled up. Therefore, with the source bed and its enrichment-rich manganese-capped and leached deposits, a set of sequences that follow one another in time is formed. There are spatial layouts that are related to each other. But each has its own unique combination of deposits. It provides a new basis for predicting prospecting.
