Eruption of Soufriere Hills Volcano

The andesitic dome-building eruption of the Soufriere Hills Volcano wreaked havoc at the small Caribbean island of Montserrat. approximately half this 'emerald Isle' was once rendered barren and uninhabitable, nearly two-thirds of the unique inhabitants needed to go away, and 19 lives have been misplaced, all as an instantaneous results of the volcanic task.

Carboniferous Geology of the Eastern United States

In regards to the ProductPublished via the yank Geophysical Union as a part of the sphere journey Guidebooks sequence. This guidebook used to be ready for a box journey to be carried out sooner than the graduation of the twenty eighth overseas Geological Congress, convened in Washington, DC, July 1989. the aim of this box journey is to ascertain the geologic elements that managed the deposition of Carboniferous rocks within the Illinois and Appalachian basins, with emphasis being put on basinal tectonic evolution, sedimentation, and paleoclimate.

Diagnosis. - Vermiceras with extremely dense ribbing throughout ontogeny. Remarks. - The development of ribbing (Fig. 4) resembles that of V palmeri (Fig. 5), but the rib numbers are far higher.

The sequence passes from the cliff into the ledges on the foreshore so that the identification of individual beds on the foreshore is easy. The facies is typical "Blue Lias", a sequence of marls and bituminous shales and intercalated marly limestone beds. Detailed sections on this part of the coast were first provided by Palmer ( 1 972, p. 70-7 1 , 73). The bed numbers of Whittaker and Green are used here, with Palmer's notation in brackets. lvimey-Cook and Donovan ( 1 983, p. 1 28- 1 29) gave a brief account of the ammonite fauna which did not permit a subdivision of the Angulata Zone, and details of the ammonite succession in the Conybeari Subzone remained uncertain.
