Diagenetic replacement of detrital albite and K-feldspar by quartz is common in Proterozoic sandstones of the Visingso Group, the Data Sandstone Formation (southern and central Sweden, respectively) and the Brottum Formation (southern Norway). The silica required for precipitation of quartz has been derived from 1) sources external to the feldspars, but which occur within the same sandstone sample, and 2) dissolution and/or replacement of the feldspars by diagenetic clay minerals. -from Authors
