摘要:

运用沉积波动分析等技术,对楚雄盆地的祥云小青坡、安龙堡、元谋洒芷、禄丰一平浪以及乌龙1井、云参1井等典型剖面进行了沉积-剥蚀特征分析,并分别建立了沉积波动方程。经分析,楚雄晚三叠世前陆盆地主要存在4种沉积-剥蚀类型,即界面型、早沉积晚剥蚀型、沉积型和早剥蚀晚沉积型。4种沉积-剥蚀类型与前陆盆地结构有很好的对应关系,造山带、逆冲推覆带、前陆凹陷带和前陆隆起带分别为界面型、早沉积晚剥蚀型、沉积型和早剥蚀晚沉积型沉积-剥蚀分布区。

Abstract:

Depositional wave analysis technique has been used to analyze the deposition and erosion characteristics of several typical profiles in Chuxiong basin,such as Xiaoqingpo in Xiangyun,Anlongbao,Sazhi in Yuanmou,Yipinglang in Lufeng,Wulong 1 well and Yuncan 1 well,and to establish their wave equations.There are mainly 4 deposition-erosion types in Chuxiong Late Triassic foreland basin,including boundary type(SB type),early deposition-late erosion type(T type),deposition type(TH type)and early erosion-late deposition type(H type).These four deposition-erosion types are in good correlation with the architecture of foreland basin.The boundary type(SB type),early depsotion-late erosion type(T type),deposition type(TH type)and early erosion-late deposition type(H type) are distributed in orogenic belt,overthrust belt,foreland hollow zone and foreland uplift zone,respectively.

Key words: foreland basin, wave geology, deposition-erosion, Chuxiong basin
