climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...

In 1893, Charles Barnes (1858-1910) proposed to designate the biological process for “synthesis of complex carbon compounds out of carbonic acid, in the presence of chlorophyll, under the influence of light” as “photosyntax” or “photosynthesis”. His preference went for the word “photosyntax”, but “photosynthesis” came into common usage as the term of choice (Gest, 2002). Although this definitio...

Since Renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. Given that Iran is benefiting from vast steppes, therate of carbon sequestration in them dese...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...

The Eocene-Oligocene transition (EOT), ~34Ma, marks a tipping point in the long-term Cenozoic greenhouse to icehouse climate transition. Paleorecords reveal stepwise rapid cooling and ice growth across the EOT tightly coupled to a transient benthic δC excursion and a major and permanent deepening of the carbonate compensation depth (CCD). Based on biogeochemical box modeling, Merico et al. (200...

global warming and climate change have drawn special attention to soil and its potential for stable carbon sequestration. soils are the largest stores of carbon in terrestrial carbon cycle and contain about three times more carbon than vegetation cover and two times more than that of atmosphere. studying the effects of grazing on soil carbon storage is important because of the major role soil o...
