Popis:	The Sikait leucogranite (SLG) is a body of porphyritic garnet granite intruded a metapelitic sequence and interlayered orthogneisses. Multiple deformation and low- to medium-grade metamorphism of the sequence was closely associated with pluton emplacement. Textural features of the SLG indicate that subsolidus plastic deformation was induced during the extensive thrusting. The granite is strongly peraluminous, alkali-rich and HFS (high field-strength) elements-depleted with low contents of REE, all facts that substantiate the geochemical characteristics of S-type granites.
