Conference paper

Abstract

The fabric of olivine in mafic and ultramafic rocks is the subject of increasingly active research ever since Andreatta (1934) published the first fabric diagrams of olivine in olivinites from Alpe Seefeld and the Cima degli Olmi in the Italian Alps. Much controversy of thought has meanwhile arisen over the kinematic and dynamic significance of the various olivine fabrics that were described in the literature, most of which are principal a-olivine fabrics in the sense that a = [010] shows preferred orientation, of either point- or girdle type, at right angles to the principal S-plane of the rock.
