Analogue and computational models principally provide our present understanding of the mechanisms of prograde metamorphism and orogenesis, yet, due to the difficulty of linking prograde age information with the pressure–temperature (P–T) evolution of a rock, these models for the most part remain untested. Here, we describe an approach that allows multiple prograde pressure–temperature–time (P–T...

Carbonate rocks are composed of carbonate minerals that chemically formed in the form solutions, and there organisms involved their formation. The limestone found around Lake Limboto is very interesting, because water lake freshwater while characteristic a marine environment. Diagenesis natural process sedimentary occurs from initial deposition until it reaches limit metamorphism will be formed...

since the ancient times, burial practices have displayed certain characteristics among different iranian ethnic groups and regions were influenced by the local religious orientations, traditions and environments, and are regarded as part of the spiritual culture of any given population. indeed, religious beliefs play the main role in this diversity. because of the empire’s long endurance and va...

Petrographical study of detrital and authigenic minerals from the Ajali Formation in Benin flank Anambra Basin was carried out with aim interpreting textural characteristics alteration patterns. Samples were collected Ayowgiri sand quarry site along Fugar-Agenebode road where good exposures Sandstone occurred. Heavy concentrated using bromoform according to standard procedures. The heavy minera...

Robat-e Zengejeh rocks affected by a variety of events began from Precambrian. This research studied preserved effects of the events. Regional metamorphism is the oldest event in this rocks include schist, amphibolite and orthogneiss, that reached up to amphibolite facies. After this regional metamorphism, it seems that mesocratic (624±5Ma) and hololeucocratic granitoides intruded respectively....

The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...

Sedimentation in the sea occurs through natural processes, such as wave and tidal action, which can be exacerbated during storms and floods. Changes in terrestrial land use, marine aggregate extraction, dredging, drilling and mining are known to result in substantial sediment deposition. Research suggests that deposition will also occur due to the modern development of marine renewable energy. ...

Sedimentation that leads to periodic, and often prolonged, burial events is becoming more common on the world's coastlines as human populations expand and create urbanised marine environments. Different seagrass species react differently to sediment burial but many species in the southern hemisphere are yet to be examined. How seagrasses react to burial has restoration implications. There is a ...

Abstract In subduction zones, materials on Earth’s surface can be transported to the deep crust or mantle, but exact mechanisms and nature of recycled are not fully understood. Here, we report a set migmatites from western Yangtze Block, China. These have similar bulk compositions as forearc sediments. Zircon age distributions Hf–O isotopes indicate that precursors sediments were predominantly ...

Seagrass meadows, one of the world's most important and productive coastal habitats, are threatened by a range of anthropogenic actions. Burial of seagrass plants due to coastal activities is one important anthropogenic pressure leading to the decline of local populations. In our study, we assessed the response of eelgrass Zostera marina to sediment burial from physiological, morphological, and...
