摘要
抚崇盆地河口组砂岩碎屑特征为：石英含量偏高,含量占碎屑颗粒总量的40%~77%,平均49%;长石含量占碎屑总量的9%~29%;岩屑种类较多,占碎屑总量的12%~35%。物源区的构造背景较为复杂,主要为活动大陆边缘和被动大陆边缘构造背景。盆地碎屑沉积物母岩主要为花岗岩类、变质岩及少量沉积岩。
The characteristics of sandstone detritus of Hekou Formation showed a high content of quartz and many types of detritus. The tectonic setting of the provenance of Fuzhou-Chongren basin is relatively complex. The provenance is mainly situated between active continental margin and passive continental margin. Parent rocks of clastic sediments in the basin are mostly granites, metamorphic rocks and small amounts of sedimentary rocks.
