Piplia Kalan eucrite: Fall, petrography and chemical characteristics

Abstract

Abstract— Two stones that fell near Piplia Kalan on 1996 June 20 are identified as Ca‐rich achondrites belonging to the eucrite group. The conditions of their fall are described. The petrographic description, texture and chemical composition, the elemental ratios, particularly K/La and Yb/Sc, and relatively flat rare‐earth‐element (REE) patterns (6–8× chondrite) of bulk samples without any significant Eu anomaly all agree with the characteristic values found in eucrites. A feldspar‐rich fraction shows a significant positive Eu anomaly. The presence of several different lithologies and clasts indicates that it is a texturally diverse breccia, and the chemical analysis suggests that it belongs to the noncumulate group of eucrites falling in the Nuevo Laredo trend.
