The Southeast Asia region is endowed with a diversity of mineral resources, notably
porphyry-related skarn, epithermal and sediment-hosted/orogenic gold deposits. Formation of these …

… The Cu porphyries are shoshonitic and high-K calc-alkaline, showing geochemical affinities
with adakites. The porphyries were derived from a thickened basaltic lower-crust source, …

… Ore-bearing granitoids are mainly monzonitic granite and K-feldspar granite with abundant
alkalis and volatile components (F, H 2 O) and a high abundance in LILE and ore elements. …

… in the Yulong belt are characterized by high K 2 O contents and enrichment in Rb and Ba, …
-enriched mantle metasomatized by components such as H 2 O, K, Rb, Ba, Th, and LREE or …

… K–S comparisons from the Himalayas and from Australia suggest that North China was
close to Gondwana, but our K–S inter-terrane comparisons do not support this hypothesis. …

Seventy skarn-type gold deposits, including 1 super-large, 19 large and 24 medium-sized,
are known from different geotectonic units of China. They contain a total resource of …

… [13] This sample contains ∼20% up to 2 cm K-feldspar augen in a recrystallized matrix of
K-feldspar, plagioclase, quartz and brown biotite with a strong tectonic fabric. Geochemically it …

The South China Region is rich in mineral resources and has a wide diversity of deposit
types. The region has undergone multiple tectonic and magmatic events and related …

… Permian WAL rhyolites are generally medium–high-K (ca. 1.81–6.22 wt.%, excluding the
few low-K rocks where this element is probably mobile), with medium–high Zr (ca. 630–800 …

… Available K/Ar radiometric data indicate significant and possibly widespread thermal
disturbances in the central granitoid belt during the Tertiary (mostly Miocence). In this study, the …
