In fact, the micro-topographic genesis of the rocky surface mortar may be interpreted differently in different places, including pothole, weathering pit, sea cave and wind-eroding pot. It is very controversial to determine this ＂glacial pothole＂.展开更多

However, these ultrahigh-pressure metamorphic rocks were found only in the southern Qinling Orogene before. In 1993, they were reported in the Qinling Group. Recently, coesites have been found in eclogites.展开更多
