乐山—龙女寺古隆起形成及其剥蚀与沉积状态研究

本文运用构造学、沉积学和地球化学等学科对乐山—龙女寺古隆起进行了综合的-体化的定量研究。它以多方面的计算结果论证了隆起面积、隆起幅度、隆起坡度、隆升速度、沉降速度、沉积厚度等,特别是剥蚀与沉积的平衡计算结果可信度达到93%,这就更深刻地揭示了古隆起形成、演化及剥蚀、沉积的规律。

STUDY OF FORMATION,EROSION AND DEPOSITION OF LESHAN-LONGNUSI PALEO UPLIFT

Such subjects as tectonics, sedimentology and geochemistry have been applied to study the formation, erosion and deposition of Leshan-Longnusi Paleo-uplift comprehensively and quantitatively. The author discussed the area, rate and slope of the uplift as well as subsidence rate, deposit thickness according to the versatile calculation results. Especially, the balance calculation result of the uplift erosion and its deposition rate is exact up to 93% and is trustworthy. The research reveals the formation, evolution and edposition of up-life。
