Pedogenesis on acid, low-grade metamorphic rocks under well-developed forests was studied in the meso-mediterranean climatic zone. To that purpose three representative soil profiles on phyllite and sandstone under sclerophyllous oak, pine and heathland were selected. The major soil forming processes ...
Precambrian highgrade metamorphic rocks (granulite facies, transitional granulite to amphibolite facies, and amphibolite facies) from the Amata area, Musgrave Ranges, central Australia, display contrasting weighted average K/Rb ratios (628, 310, and 203 respectively). This pattern of higher K/Rb ...
Quartz preferred orientations with c-axes parallel to stretching directions are widespread in slates, phyllites and very low-grade schists of the South Island, New Zealand. In general, these rocks lack evidence for plastic deformation of quartz and often preserve the original clastic quartz which ...
The ultramafic rocks as enclaves are widespread distributed in TTG gneisses from the Early Precambrian metamorphic high-grade basement of Shandong Peninsula,SE North China Craton (NCC).A combined study of petrography,mineral transformation,temperature-pressure estimation and in situ U-Pb dating of zirco...
