揚子江下游“矽卡岩型”矿床許多年来均被认为是远景不大的一种矿床。解放后十数年来的地貭勘探工作对本区的这种矿床有了进一步的了解。事实上,所謂的“矽卡岩型”矿床包括了許多不同类型和远景大小不一的矿床。因此在矿床評价方面常常仅以“矽卡岩型”来分类会导致目的不明,优劣不分,終于对一个有远景的矿区躊躇不前;而对于远景小的矿区則反复周旋,迟疑不决。
The “skarn-type” deposits in the lower reaches of the Yangzi River have for many years been considered as a deposit of little prospect. In the past ten years after liberation, the geo-exploration work has further understanding of this deposit in this area. In fact, the so-called “skarn-type” deposits include many different types and prospects of mineral deposits of different sizes. Therefore, the classification of “skarn-type” in the evaluation of deposits usually leads to the unknown purpose, regardless of the pros and cons, and finally hesitates to a prospective mining area; while for the prospect of small mining areas, it is repeatedly dealt with and hesitated .
