Background: Orbital remote sensing observations over the past decade have shown Mars to host a great diversity of hydrous minerals, including clays, sulfates, zeolites, and opaline silica [1-3]. Though certain regions of Mars contain vast exposures of these minerals (e.g., clay minerals in Mawrth Vallis and Nili Fossae and sul-fates in the interior layered deposits of Valles Mari-neris), many o...

While the structural study of biomaterials recently seems to be attracting increasing attention in crystallographic effort, mineralogy formed a foundation for modern crystallography and there are still many open important questions in this field. Highlights in Mineralogical Crystallography was written to describe some of these hot topics. To broaden the field of vision of the book, it was writt...

Minerals are more complex than previously thought because of the discovery that their chemical properties vary as a function of particle size when smaller, in at least one dimension, than a few nanometers, to perhaps as much as several tens of nanometers. These variations are most likely due, at least in part, to differences in surface and near-surface atomic structure, as well as crystal shape...

The Main Glauconite Bed (MGB) is a pelleted greensand located at Stone City Bluff on the south bank of the Brazos River in Burleson County, Texas. It was deposited during the Middle Eocene regional transgression on the Texas Gulf Coastal Plain. Stratigraphically it lies in the upper Stone City Member, Crockett Formation, Claiborne Group. Its mineralogy and geochemistry were examined in detail, ...

Introduction: In the quest for search of novel pharmacotherapy from medicinal plants psychiatric disorders, it has progressed appreciably past few decades and their therapeutic potential been evaluated in a variety murine models. Cassia singueana Del. is commonly used plant Nigeria management insanity as lactation enhancer. Aim: The main aim this study was to evaluate cognitive extract against ...

Mineral identification is an important part of geological analysis. Traditional methods rely on either the experience appraisers or various measuring instruments, and are easily influenced by appraisers’ require too much work. To solve above problems, there studies using image recognition intelligent algorithms to identify minerals. However, current cannot many minerals, accuracy low. increase ...

the study area is located at the sanandaj-sirjan zone in the west and north-west of azna and north-east of doroud, iran. the quartz-schists are divided into two main groups: amphibole-quartz schist and garnet-quartz schist. field and microstructural studies show several deformational phases. the d1 episode which is represented by s1, matches with m1 metamprphism and d2 deformation matches with ...

The new approaches of the animal production systems make managing the mineral nutrition a challenge. Versus the excessive, trace mineral supply in intensively managed livestock, well above the physiological requirements, is the no trace mineral supplementation of organic systems, which become highly dependent on trace minerals in the soil. Nowadays, in addition to the animal health perspective,...
