متن کاملGeochemical Study of Some Howardites and Polymict Eucrites
Introduction: Howardites and polymict eucrites are polymict breccias composed of eucrites, diogenites and other lithologies [1, 2, 3]. Previous studies showed that howardites contain chondritic clasts [e.g., 4, 5]. Howardites and polymict eucrties may contain metals which are related to impactors [6, 7, 8]. On the basis of chemical composition and mineralogical data, we will discuss the provena...
