In sections below the isotropic gabbro , which show layering , lateral continuity of the fine-scale igneous layering is generally lacking , and the layers tend to pinch out over lateral distances equivalent to outcrop scales . Primitive mantle-derived MORB magmas forming discrete magma chambers in the crust should generate the same type of cumulates observed in ophiolites or layered intrusions but within each small intrusion . Naturally spawning populations in tributaries upstream of hatchery release sites have apparently undergone limited introgression by hatchery stocks , based on CWT recoveries and genetic analysis ( Chapman et al. 1995 ) . The large-scale units defined in ophiolites generally consist of interlayered intervals with distinctive rock types , such as troctolite , pyroxenite , or oxide gabbro . It was not clear whether the government will contend Moussaoui was to play a role on Sept. 11 or in attacks planned for a later date . The final chapter highlights how women were welcomed into the Republican party in 1920 and 1924 when the Nineteenth Amendment was passed and more women had the opportunity to enroll in parties and vote in the national election . The fine-scale ( centimeter to meter scale ) layers in ophiolites cannot be followed laterally for more than ~ 100-200 m and commonly much less because they pinch out .
