1994 REPORT ON WHIN SILL DOLERITE WS-E FROM ENGLAND AND PITSCURRIE MICROGABBRO PM-S FROM SCOTLAND - ASSESSMENT BY 104 INTERNATIONAL LABORATORIES

This compilation report describes the field location, mineralogy, prep aration and homogeneity testing of two new GIT-IWG reference materials : Whin Sill dolerite (WS-E) from England and Pitscurrie microgabbro (P M-S) from Scotland. The elemental composition of these two new referen ce materials has been established by an international cooperative anal ysis programme involving participation by 104 laboratories. A full ass essment of these analytical results is presented, from which working v alues have been derived for the major elements as well as for 45 trace elements in WS-E and 44 trace elements in PM-S. Furthermore, isotopic ratios are presented for both samples, particularly for Sr-87/Sr-86 a nd Nd-143/Nd-144.
