A seismogeological model of the junction zone Nepa-Botuoba anteclise and Ygyattinskaya depression was built based on results a comprehensive interpretation deep drilling seismic data. The position propagation regional high-rank faults have been specified, tectonic study area has constructed. All were divided into three classes: those that cut entire sedimentary cover; developed in lower part se...

We report composition and age data from a restricted <370 km2, volcano-sedimentary basin beneath Mesozoic cover to the northwest of Flinders Ranges, South Australia. This comprises two components: sedimentary sequence that includes shales, siltstones sandstones, basalt–sedimentary member. Together, these components are defined as Ooloo Hill Formation. Whole-rock K–Ar geochronology for five basa...

23 24 Large rounded pyrite grains (>1 mm), commonly referred to as ‘buckshot’ pyrites, are a characteristic feature of 25 the auriferous conglomerates (reefs) in the Witwatersrand and Ventersdorp supergroups. Detailed petrographic 26 analyses of the reefs indicated that the vast majority of the buckshot pyrites are of reworked sedimentary origin, 27 i.e., that the pyrite originally formed in th...

The sedimentology and palaeogeography of some Devonian sedimentary rocks in southwest Ireland

We consider various hitting and piercing problems for the family of axis-parallel rectangles induced by a point set. Selection Lemmas on induced objects are classical results in discrete geometry that have been well studied and have applications in many geometric problems like weak epsilon nets and slimming Delaunay triangulations. Selection Lemma type results typically bound the maximum number...

A common subproblem of $DNF$ approximate counting and derandomizing $RL$ is the discrepancy problem for combinatorial rectangles. We explicitly construct a $poly(n)$size sample space that approximates the volume of any combinatorial rectangle in $[n]^n$ to within $o(1)$ error (improving on the constructions of [EGLNV92]). The construction extends the techniques of [LLSZ95] for the analogous hit...

Burial of organic carbon in marine sediments has a profound influence in marine biogeochemical cycles and provides a sink for greenhouse gases such as CO2 and CH4. However, tracing organic carbon from primary production sources as well as its transformations in the sediment record remains challenging. Here we examine a novel but growing tool for tracing the biosynthetic origin of amino acid car...

A thick succession of sedimentary rocks belonging to Tipam Group is well exposed all along the road cut sections near Buhchang village, Kolasib district, Mizoram. The heavy mineral suite of the Tipam sediments depicts a cosmopolitan nature. It comprises dominantly of non-opaque variety that includes zircon, tourmaline, rutile, staurolite, kyanite, sillimanite, apatite, epidote, garnet and hornb...
