a faunistic list of syrphidae sampled in the agroecosystems of neyshabur (khorasan-razavi province) through malaise, yellow water traps and hand net is hereby presented for the first time. a total of 22 species were collected, including 13 species through malaise trap, 5 through yellow water trap as well as representatives of all species sampled through hand net. among the species collected, 8 ...

anomolously low A1203, low Ti02 and are enriched in chromium and nick~A We present petrographic and chemical c ata on the Kamloops Lake picritic tmalts as we1 I as the stratigraphic setting for thwe ultramafic lavas. Age constraints derive From field relationships, Mineral chemistry indicates th 31 these ultramafic rocks represent mantle-deri.ed material which has undergone: minimal differentia...

S U M M A R Y Geophysical inversion is often ill-posed because of inaccurate and insufficient data. Regularization is often applied to the inversion problem to obtain a stable solution by imposing additional constraints on the model. Common regularization schemes impose isotropic smoothness on solutions and may have difficulties in obtaining geologically reasonable models that are often suppose...

Your story matters. 8 The geologic sequestration of carbon dioxide (CO 2) in structural and stratigraphic 9 traps is a viable option to reduce anthropogenic emissions. While dissolution of the 10 CO 2 stored in these traps reduces the long-term leakage risk, the dissolution process 11 remains poor...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

the qom formation, a series of shales, sandstones and carbonate deposits, is the last transgression of the sea in central iran sedimentary basin. foraminifera are one of the most important and numerous fossil groups present in the qom formation. in this study, the micropaleontology of the qom formation in three measured stratigraphic sections in south and west of tafresh (rakin, band-e-ali nagh...

The geologic sequestration of carbon dioxide (CO2) in structural and stratigraphic 9 traps is a viable option to reduce anthropogenic emissions. While dissolution of the 10 CO2 stored in these traps reduces the long-term leakage risk, the dissolution process 11 remains poorly understood in systems that reflect the appropriate subsurface geometry. 12 Here, we study dissolution in a porous layer ...
