Quantitative textural measurements in igneous and metamorphic petrology by Michael Denis Higgins( )

18 editions published between 2006 and 2010 in English and held by 878 WorldCat member libraries worldwide

Paperback Re-issue: Processes involved in the development of igneous and metamorphic rocks involve some combination of crystal growth, solution, movement and deformation, which is expressed as changes in texture (microstructure). Advances in the quantification of aspects of crystalline rock textures, such as crystal size, shape, orientation and position, have opened fresh avenues of research that extend and complement the more dominant chemical and isotopic studies. This book discusses the aspects of petrological theory necessary to understand the development of crystalline rock texture. It develops the methodological basis of quantitative textural measurements and shows how much can be achieved with limited resources. Typical applications to petrological problems are discussed for each type of measurement. This book will be of great interest to all researchers and graduate students in petrology
A geological companion to Greece and the Aegean by Michael Denis Higgins( Book )

12 editions published in 1996 in English and held by 381 WorldCat member libraries worldwide

Using the term geology in its broadest sense, Michael Denis Higgins and Reynold Higgins not only describe the bedrock and the geomorphology of Greece and the Aegean region but also discuss ancient sources of water, stone, and metals in relation to the development of settlements. They explore the links between archaeology and geology, asking how the geological environment shaped settlement in antiquity and how subsequent geological processes have influenced the preservation or destruction of ancient sites. The authors begin with an outline of the geological background and explain some of the geological controversies of the area. They catalogue what could be seen on the surface of the earth and consider, as well, the processes that resulted in those surface features. Their general survey is followed by the treatment of individual sites within settlements. A Geological Companion to Greece and the Aegean includes over 140 maps, as well as space-shuttle photographs, a glossary, and references to original sources. It will interest scholars and archaeologists and will also appeal to those who visit ancient sites and are eager to be fully informed
Age and origin of the Sept Iles anorthosite complex, Quebec by Michael Denis Higgins( )

4 editions published between 1979 and 1982 in English and held by 6 WorldCat member libraries worldwide

"Rb-Sr studies of the Sept Iles anorthosite complex show that it was emplaced during the Cambrian and that it is unrelated to the Grenville province. The age of this complex is very similar to that of other igneous rocks associated with the St. Lawrence graben system. Both the acidic and basic components of the complex have similar ages and originated from magmas with similar, low('87) Sr/('86) Sr initial ratios. There is no evidence that crustal contamination played an important role in the generation of the acidic magmas. The earliest rocks of the complex exposed at Sept Iles are now observed on the mainland. They consist of cumulates rich in oxide minerals, mafic minerals and plagioclase. These rocks are thought to have been formed at the base of the complex. Further south, across the fault that defines the St. Lawrence graben in this area, the top of the complex is exposed on six islands and Presque-Ile Marconi. This part of the complex is thought to have formed by multiple injection of the magma differentiating at depth in the main chamber into the already solidified roof of the complex. Plagioclase cumulates, the earliest rocks exposed here, are cut by later, more differentiated gabbros. Syenite commonly overlies the basic rocks and is in turn overlain by granite. Geochemical and petrographic evidence indicate that the syenite was intruded as a magma and was not formed by accumulation of perthite precipitated from the granite. Geochemical studies show that all the rocks exposed at Sept Iles could have been formed by differentiation of a single gabbroic magma."--
