洞穴碳酸钙是洞穴中分布最广的一种洞穴矿物沉积,它在洞穴内的堆积形成了千姿百态的洞穴碳酸钙沉积形态,国内外的洞穴科学工作者对其沉淀机制、速度和形态成因等诸方而做了大量的工作。然而,对这些工作结果的认识还存在着不少分歧。作者认为,洞穴碳酸钙的形成是借助于水这个媒介物质,水运动条件的变化,首先对沉淀的物理化学条件产生重大影响,使沉淀的情况有所改变;其次,按照水运动条件等因素划分的洞穴水类型与洞穴碳酸钙形态形成密切相关。同时,由于沉淀和溶解是互逆反应,碳酸钙沉淀理论的解决将导致喀斯特溶蚀理论的完善。因此,本文对上述问题进行了初步研究,文中的重点是一些尚有分歧和尚待解决的问题。
Cavern Calcium Carbonate is the most widely distributed cave mineral deposit in caves. Its accumulation in caverns forms calcareous deposits of calcium carbonate in various forms. Cavern scientists at home and abroad have made great achievements in sedimentation mechanism, velocity and morphogenesis And do a lot of work. However, there are still many differences on the understanding of the results of these work. The authors believe that the formation of cave calcium carbonate by means of the media of water, the change of water movement conditions, first of all have a significant impact on the physical and chemical conditions of the precipitation, the precipitation of the situation has changed; Secondly, in accordance with the water movement conditions and other factors The type of cave water is closely related to the formation of cave calcium carbonate. At the same time, since precipitation and dissolution are reciprocal reaction, the solution of calcium carbonate precipitation theory will lead to the improvement of karst erosion theory. Therefore, this article has carried on the preliminary research to the above-mentioned questions, the key point in the article is some problems that still have the disagreement and yet to be solved.
