摘要
1987—1988年,在塔里木盆地北部的库车一轮台地区进行了热流测量,取得了西北地区的首批热流值。研究区在地质上属雅克拉一轮台基岩隆起带,巨厚的中新生界陆相碎屑岩不整合于古生界及前古生界基岩之上。西段雅克拉地区在深约5400m 的不整面之下为下古生界碳酸盐岩,上覆厚仅数十米的侏罗系及厚约5300m 以上的下白垩统一第四系,在侏罗系及下白垩统之间有一沉积间断。
The first set of terrestrial heat flow values in Northwest China was measured in Yakela- Luntai ares on the northern side of the Tarim basin,where exsists an basement uplift com- posed of Cambrian and Ordovician carbonate rock and Pre-cambrian metamorphic rocks co- vered with Meso-Cenozoic sediments over 5000m.The heat flow value is 43.93mW/m^2 on the western side of the studied area at Yakela and 44.34mW/m^2 on the eastern side at Luntai,and 44.14mW/m^2 in anerage.The result is consistent with the stable tectonic regime of the Tarim basin and suggests the lower thermal regime of this oil-bearing area then that of the eastern oil-bearing basin.
