Scientific paper

Two stones that fell near Piplia Kalan on June 20, 1996 are identified as Ca-rich achondrites belonging to the group of eucrites. 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 REE patterns (6-8 x 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 europium anomaly. Presence of several different lithologies and clasts indicate that it is a texturally diverse breccia and the chemical analysis suggests that it belongs to non-cumulate group of eucrites having Nuevo Laredo trend.
