Three of these most recent volcanic events are studied. French 44 English 10 Chinese 2. Most widely held works by Bernard Bonin. The glossary of igneous terms has been fully updated since the first edition and now includes entries, of which are recommended by the Subcommission.

Huan zhuang hua gang yan za yan ti by Bernard Bonin Book 2 editions published in in Chinese and held by 4 WorldCat member libraries worldwide. By mineralogical studies, the location of the sub volcanic domain of the Mont-Dore has been determined at 0.

The Mont-Dore volcano, stricto sensu, presents several enclave families: The Sancy enclaves are distinct from those of the Mont-Dore volcano; two different types of enclaves have been flassification Two types of glass morphology can be distinguished SEM angular fragments are considered as old pulverized mesostases, and pumiceous glasses are mqgmatiques as products of new magma. The daly gap which exists at the benmoreitic step in the volcanic series of Mont-Dore disappears when considering also the plutonic series; the whole suite forms a complete alkaline series where the daly gap corresponds to a silica-undersaturated monzonite liquid which yielded bath differentated liquids and cumulate formations.


They are close to each other but petrographycally different. They were chosen in an active margin Santiaguito, Guatemalaas well as in island arcs St.

Moreover, by mineralogical studies in conjunction with chemical studies of trace-elements, a magma chamber classificatkon evidenced at not too great depths 8 kmwhere a differentiation process occurs from a monzonitic primary magma by fractionation of amphiboles, pyroxenes and plagioclases. Two of these factors play a more significant role high volatile contents essentially water of deep or superficial originand magma-mixing. Incorporating a comprehensive bibliography of source references for all the terms included in the glossary, this book is an indispensable reference guide for all geologists studying igneous rocks, either in the field or the laboratory.

These two factors modify the thermodynamical conditions in the magmatic chamber and facilitate the magma vesiculations.

W Le Maitre 2 editions published in in English and held by 59 WorldCat member libraries worldwide “Decades of field magmatiwues microscope studies, and more recent quantitative geochemical analyses have resulted in a vast, and sometimes overwhelming, array of nomenclature and magmatiquee associated with igneous rocks.


Magma-crust interactions and evolution: This atoll is composed of submarine volcanic rocks overlaying the oceanic crust, then aerial volcanic rocks, and finally corals, about m thick. Magmatic trend is restricted to basalts and hawaiites with less alkaline affinities: No Sancy enclave is issued directly from the magma chamber; all these enclaves have been produced by rapid high-temperature crystallization under a low Hpressure.

Their chemical variations testify sometimes for magma-mixing. Their petrography and mineralogy are typical of andesitic trends.

It presents a standardised and classitication accepted naming scheme that will allow geologists to interpret terminology in the primary literature and provide formal names for rock samples based on petrographic analyses.
