| 内容記述 | Autoclastic rock is referred to as a volcanic-intrusive rock produced by superepizonal crypto-explosion. A specific kind of autoclastic volcanic-intrusive rocks has been found in many localities of southeastern China. These rocks are formed in late Jurassic to early Cretaceous. In southeastern China, the occurrence of these autoclastic volcanic-intrusive rock bodies is generally controlled by northeasterly oriented regional faults. Tonglu body is a good example of these rocks, and is distributed along NE direction. In Tonglu volcanic basin, the rocks of three stages are all exposed owing to a deeper denudation. First stage volcanic rocks: rhyolitic and rhyodacitic volcanic rocks are distributed along the border of basin. Third stage hypabyssal intrusive body represented by aegirine-riebeckite bearing quartz monzonitic porphyry occupies its central part. Between them, Second stage subvolcanic rock with porphyroclastic texture, i.e., the autoclastic adamellite porphyry occurs. These rocks combine together giving a three-fold centripetal structure, and are comagmatic. In the autoclastic adamellite porphyry, a specific "overgrowth border" around crystallinoclastic orthoclase is often found. Many pearlitic quartz grains are mosaiced in orthoclase border. It is called "pearlitic border." The pearlic border is developed not on]y around crystallinoclastic orthoclase but also around crystallinoclastic plagioclase, quartz and hornblende in the autoclastic adamellite porphyry. The chemical composition of pearlitic border mineral shows intermediate properties between crystallinoclastic mineral and groundmass mineral. The pearlitic border is considered to be formed as a reaction rim between crystallinoclast and groundmass under autoclastic environment. | |||||
