Piplia Kalan eucrite: Fall, petrography and chemical characteristics

— 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.
