the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

People use fish to meet their needs. Fish utilization and economic activities in the neritic tuna’s fishery system at Pasongsongan were an effort achieve social welfare. However, uncertainty surrounding caused a risk fishermen's income stability. Those are conducted this research identify elements of social-ecological tuna fisheries assess based on daily prices. Identification followed framewor...

The genus Coolia A. Meunier 1919 has a global distribution and is common member of epiphytic dinoflagellate assemblages in neritic ecosystems. monotis the type species was only known for 76 years. Over past few decades, molecular characterization unveiled two complexes that group morphologically very similar species, so their limits are often unclear. To provide new knowledge on biogeography co...

A Miocene succession exposed at the Cabo Ledo and Miradouro da Lua sections in Onshore Kwanza Basin, Angola, was examined for palynology. Palynomorphs of preliminary late age identified are presented herein. The upper part Quifangondo Formation is dated as middle Tortonian based on co-occurrence pollen grain Fenestrites spinosus dinoflagellate species Selenopemphix armageddonensis. palynomorph ...

This work introduces one of the first palynostatigraphic study conducted on formations from Eocene and overlying lowermost Miocene successions (Cunga Quifangondo formations) exposed in Onshore Kwanza Basin, Angola. To improve Cunga age, new biostratigraphic correlations palaeoenvironmental interpretations based qualitative quantitative analyses organic walled dinoflagellate cysts sedimentary ro...

The present study determined the distribution and biomass of Peruvian anchovy pelagic red squat lobster related to oceanographic characteristics in marine protected area Paracas National Reserve Northern Humboldt Current System. Acoustic, biological, information was collected on habitat surveys carried out by Marine Research Institute during summer spring 2018, 2019, 2020. results obtained indi...
