Typical D.T.A. peak systems yielded by the fresh lower Ecca shales in the Durban and Pietermaritzburg areas are presented. The theoretical course of recrystallisation for these rocks is derived from chemical thermodynamic data. These theoretical results agree well with experimental observation. Carbon is found to dictate the course of recrystallisation on the basis of overall chemical rather th...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...

Stromatolites are found throughout the geological record and have received strong attention because they provide precious information about paleoenvironments microbial paleobiodiversity. However, while this is interpreted based on our knowledge modern analogs, latter remains incomplete. Here, we investigated environmental biological recorded by stromatolites in Mari Ermi, a coastal pond Western...

Exposure to coal dust from mining-related activities has historically been linked several preventable but incurable respiratory diseases. Although the findings of numerous biological studies have determined that physicochemical and mineralogical aspects particles greatly influence both cytotoxic proinflammatory pathways, robust datasets which quantitatively define these characteristics remain l...

[1] The last major phases of lunar volcanism produced spectrally unique high‐titanium basalts on the western nearside of the Moon. The Moon Mineralogy Mapper (M) on Chandrayaan‐1 has provided detailed measurements of these basalts at spatial and spectral resolutions necessary for mineralogical interpretation and mapping of distinct compositional units. The M3 imaging spectrometer acquired data ...

Natural mineral dust storms (DS) from the Arabo-African region blow over the Mediterranean, reach Israel, and add to the anthropogenic particulate pollution. The effects of mineral dust on air quality in Israel were investigated using only PM10 and PM2.5 automatic measurements. The method does not require any other inputs such as satellite observations, model back-trajectories, dust forecast mo...

This work studies mineralogical data from X-Ray Diffraction Techniques (XRD) and geochemical data analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) of fine fraction from samples collected along the Ocean Margin Exchange Project (OMEX) core KSGX 24. This core was recovered in the external sector of Ria de Vigo, N Spain. Radiocarbon ages allowed the estimation of an age about 3 ka...

A principal goal of the Mars Science Laboratory (MSL) rover Curiosity is to identify and characterize past habitable environments on Mars. Determination of the mineralogical and chemical composition of Martian rocks and soils constrains their formation and alteration pathways, providing information on climate and habitability through time. The CheMin X-ray diffraction (XRD) and X-ray fluorescen...

BACKGROUND Between 1997 and 1999 three sericite plant workers in Parana, Brazil, were diagnosed with pneumoconiosis. AIMS To investigate and describe the radiological, clinical, and pathological changes in miners and millers exposed to sericite dust with mineralogical characteristics of inhaled dust. METHODS The working premises were visited to examine the sericite processing and to classif...

More than half of the >5000 approved mineral species are known from five or fewer localities and thus are rare. Mineralogical rarity arises from different circumstances, but all rare mineral species conform to one or more of four criteria: (1) P-T-X range: minerals that form only under highly restricted conditions in pressure-temperature-composition space; (2) Planetary constraints: minerals th...
