德干玄武岩是世界上最大的大陆溢流玄武岩之一,通常认为具有大致均一的化学成分。然而近几十年来,对德干台拉岩(Trap)的研究日趋活跃,现已查明西部的德干台拉岩无论在构造、岩石或化学成分上都有所不同。本文报道了萨加尔地区下部台拉岩中低钾拉斑玄武岩的产出,同时还表明另外一些地区,例如坦杜尔的台拉岩也属于这个范畴。本文考虑到德干台拉岩的构造、岩石、地球化学以及地质年代方面的差异,根据一般公认的模式,对这些低钾的石
Durban basalt is one of the largest continent-overflow basalts in the world and is generally considered to have a generally uniform chemical composition. However, in recent decades, research on Trap has become increasingly active. It has been ascertained that there are differences in tectonic, rock or chemical composition in the western Degancha. This paper reports the production of low-kalla rock basalts from the Lower Protola in the Sagar area and also indicates that other areas, such as the Melange in the Tandur, also belong to this category. Considering the differences in the tectonic, lithological, geochemical, and geochronological aspects of the Teghantala rocks, this paper, based on a generally accepted model,
