Book excerpt: Mapping, petrological studies, and U-Pb (zircon) dating have identified four bimodal plutons herein named Gillis Brook, Leonard MacLeod Brook, Easach Ban, and Barren Brook in the southern part of the Ganderian Aspy terrane in Cape Breton Island. The plutons consist mainly of gabbroic to dioritic rocks and syenogranitic rocks which are closely associated and locally display mingled relationships with one another, consistent with their similar ages of ca. 435-430 Ma. They display alkalic to calc-alkalic chemical signatures and it is not clear if they formed in a subduction-related magmatic arc or within-plate extensional setting. They were emplaced at shallow depth and are co-magmatic with their Silurian volcanic and sedimentary host rocks of the Sarach Brook Formation. They are petrologically distinct from and not related to the younger (Devonian) and entirely granitic Bothan Brook pluton which also intruded the Sarach Brook Formation in the same area. None of these plutons shows evidence for significant economic mineralization potential. In contrast, the Devonian Gillis Mountain pluton in the Avalonian Mira terrane of southern Cape Breton Island hosts porphyry-style copper-molybdenum mineralization. New studies of trace element characteristics of surface and drill core samples from the Gillis Mountain pluton confirm previous work which showed that it is calc-alkalic and emplaced in a subduction zone setting, intruded into Cambrian shale and siltstone. The presence of sulphide minerals and elevated background metal contents are evidence of its economic potential. Comparison of these plutons shows contrasts in field and petrological characteristics. These differences are consistent with the fundamental distinction between the Aspy and Mira terranes in terms of origin, geological evolution, and tectonic setting through to the Devonian.

Available in PDF, EPUB and Kindle. Book excerpt: As a UNESCO World Heritage Site, the Joggins Fossil Cliffs offer an unprecedented glimpse into the Earth's history. Bearing fossils of organisms from the lush, tropical forests that existed in the Coal Age — when the continents were assembled into one huge land mass or supercontinent, Pangea — Joggins traces, through layers of sediment, the massive environmental and geologic shifts that have occurred in the planet in the intervening millennia. From fossilized trees that stood thirty metres high to the remains of the earliest known reptile, Hylonomus lyelli, Joggins holds important information about the development of life on Earth — including offering lessons about human impacts on the environment. The Cliffs also share a story of human tenacity and rigorous debate on historical theories of evolution. Sir Charles Lyell and Sir William Dawson, two early geologists who studied Joggins extensively, influenced Charles Darwin with their findings of early fossil remains, particularly hollow tree fauna. The extent of their research at the Joggins site remains unparalleled and significant to this day. The book outlines these stories and more, including Mi'kmaq settlement of the area and the rise of the coal mining industry in the 19th century. It also shares the perspectives of Joggins residents today, and their efforts to preserve this globally significant location and the precious historical information it holds.

Download or read book Bergsonism written by Gilles Deleuze and published by Princeton University Press. This book was released on 1988-03 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this analysis of one major philosopher by another, Gilles Deleuze identifies three pivotal concepts - duration, memory, and lan vital - that are found throughout Bergson's writings and shows the relevance of Bergson's work to contemporary philosophical debates. He interprets and integrates these themes into a single philosophical program, arguing that Bergson's philosophical intentions are methodological. They are more than a polemic against the limitations of science and common sense, particularly in Bergson's elaboration of the explanatory powers of the notion of duration - thinking in terms of time rather than space.
