A New Geochemical Reference Sample of Granite (DG-H) from Dalhousie, Himachal Himalaya

A new geochemical reference sample of Granite named as DG-H from Dalhousie, Himachal Pradesh is proposed for collaborative study. The sample has been tested for its suitability as a reference standard in terms of its bulk homogeneity using F-test carried out for 16 fractions of the sample analysed in duplicate. The relevant information like, location, geological set-up, mineralogical make-up, petrography, expected chemical composition and F-ratios derived for major oxides are given for the benefit of potential contributors and users. The proposed standard may prove useful for analysis of granitic rocks with high Cr and lower abundances of elements like Ba, Ca, Cu, Nb, Ni, Sr, Th, Y and Zr.
