Reply to Comment on "Corundum-bearing garnet peridotites from northern Dominican Republic: A metamorphic product of an arc cumulate in the Caribbean subduction zone" by Richard N. Abbott and Grenville Draper

Abstract : In our Reply to the Comment by Abbott R.N., Jr., Draper, G., 2010. Comment on “Corundum-bearing garnet peridotite from northern Dominican Republic: A metamorphic product of an arc cumulate in the Caribbean subduction zone” by Hattori et al. Lithos 114 (2010) 437–450]. Lithos 117, 322–326 (this issue), we clarify several points concerning the origin of garnet (Grt)-bearing ultramafic rocks in Dominican Republic, and provide new trace element data from additional samples that contain varying amounts of loss on ignition (LOI). These new data verify that the trace element signature of these bulk rocks reflect those of their primary rocks, and are not significantly affected by low-temperature alteration. These new geochemical data reconfirm the interpretations in our paper (Hattori et al., 2010a) that Grt-bearing ultramafic rocks crystallized as cumulates of arc magmas at shallow levels in the mantle wedge, and were later metamorphosed in the subduction channel to form Grt.
