江西永豐縣南,古縣至瑤田間之梁坊橋附近,有一變形礫岩層,恰位於走向北10度東及北80度东兩逆斷層啣接處。該礫岩層中之礫石,多為扁平橢圓形,其長軸兩端逐漸尖化,外附絲澤、臘狀、光滑表皮,並有新生之雲母片及長纖維狀物質,於此光滑面上,常具深刻水平擦痕。這些變形礫石,受外力變形後,共長軸近於東西,扁平面平行於北80度東之斷層面舆附近岩層之片理。垂直變形礫石a,b,c三軸及膠結物質延長方向,分製薄片,在顯微鏡下觀察,其膠結物為灰白色雲母及許多無光性之黑色物質,呈顯著之流紋構造,內含大小不一之眼球狀石英粒等;石英礫石內之石英晶體,均具極强之波浪消光,於晶體四周,圍繞密擠再結晶之小型石英粒,而示標準磨碎構造。晶體本身含有無數極小之氣孔或包體,並作一定方向排列,而成變形紋理,平行於扭應面;在石英岩礫石內,石英粒均沿一定方向延長,並按其大小作帶狀排列。礫石內部,擁有極複雜之節理舆顯明之断層,這些事實象微着强烈的外力作用。根據弗氏旋轉台再結晶石英粒。軸及雲母底面等之統計舆分析,得知其晶體排列恆受扭應力支配。
There is a deformed conglomerate layer in the south of Yongfeng County, Jiangxi Province, near Liangfang Bridge between the ancient county and Yaoyao. It is just at the junction of east and north 80 degrees to the east and north two degrees to the north of 10 degrees to the north. The gravel in the conglomerate layer, mostly flat oval, its long axis at both ends of the gradual apex, with silk, waxy, smooth skin, and the new mica and long fibrous material on this smooth surface , Often with deep horizontal scratches. These deformed gravel, after the external deformation, a total of nearly long axis of things, the flat surface parallel to the north 80 degrees east of the fault area near the rock formations. Vertically deformed gravel a, b, c axis and cemented material extending the direction of the sub-slice, observed under a microscope, the cementitious material for the white mica and many non-light black material was significant stream structure, containing the size Different from the eye-like quartz grains; Quartz gravel in the quartz crystal, are extremely strong wave extinction in the crystal around the dense recrystallization of small quartz grains, and showed the standard grated structure. Crystal itself contains numerous tiny pores or inclusions, and arranged in a certain direction, and into the deformation texture, parallel to the twisted surface; in quartzite gravel, quartz grains are extended along a certain direction, and according to their size for the band arrangement . Inside the gravel, with extremely complex joints show obvious faults, these facts are like a strong external force. According to the Freunds rotating table recrystallized quartz tablets. Axis and mica underside and other statistical analysis, that the crystal arrangement constant torsional stress dominated.
