Re-Os geochronology and geochemistry of Proterozoic sedimentary successions
… geochronology data from Proterozoic sedimentary successions and insights into Re-Os systematics of organic-rich sedimentary rocks and petroleum products such as bitumen and oil. New Re-Os ORS geochronology from two drill cores indicate that the Proterozoic Atar Group of the Taoudeni basin, …

High-resolution sequence stratigraphy and diagenesis of mixed carbonate/siliciclastic successions.
… distribution of diagenetic features in nearshore successions can be explained within a sequence stratigraphic concept; to assess whether the identification and analysis of these features can be used to aid in making sequence stratigraphic interpretations; and to evaluate whether sequence …

Chemostratigraphy of the Early Paleoproterozoic carbonate successions (Kaapvaal and Wyoming cratons)
Evidence of three glaciations in Paleoproterozoic successions of North America and at least one on three other continents, suggests that these glaciations were of global extent. In common with the Neoproterozoic record, carbonates cap the glacials. However, the relationship between biogeochemical …

From Music Theory to Graph Theory: Analyzing Chord Successions in J.S. Bach’s Modal Chorales
… I will map out the frequency of adjacent chord successions in Bach’s modal chorales, focusing on the last phrase that confirms the modal identity of each chorale. My research will provide insight into the harmonic structure of Bach’s modal chorales.

FORAMINIFERAL DISTRIBUTION AND SEQUENCE STRATIGRAPHY OF OXFORDIAN SUCCESSIONS IN THE WESSEX/ANGLO-PARIS BASIN
… study of two Upper Jurassic, Oxfordian successions from the South . Dorset Coast, U.K. and the Normandy Coast, France provide the basis for this study. A near continuous succession of the Oxfordian from South Dorset and Normandy were obtained, and foraminifera extracted. Examination of …

High-Resolution Correlation Using Geophysical and Geochemical Methods on Three Cambrian Drumian Marine Sedimentary Successions in The House Range Embayment, Western Laurentia
The Global boundary Stratotype Section and Point (GSSP) of the base of the Cambrian Drumian Stage was defined at 62 m above the base of the Wheeler formation, at the First Appearance Datum (FAD) of Ptychagnostus atavus (P. atavus), and at 10 meter below the DrumIan Carbon isotope Excursion (DICE) …

The soil seed bank in Agathis australis (D. Don) Lindl. (kauri) forests of northern New Zealand and its potential role in secondary successions
… quantified, and its potential role in secondary successions examined. Seed bank data from a number of kauri forest sites stratified by successional time and distance from forest edges are summarized using Detrended Correspondence Analysis (ordination) and linear regression models. A number of …

Significance of magma mingling and mixing during the formation of the host-rock successions of Archean massive sulfide deposits in the Noranda camp, Abitibi subprovince, Quebec, The
The Noranda mining district contains some of the most important volcanic-hosted massive sulfide deposits of the Neoarchean Abitibi subprovince of northern Ontario and Quebec. With a historic production of 54.3 Mt of ore grading 2.2% Cu and 6.1 g/t Au, the Horne deposit was the largest base and …

Late Pleistocene lithofacies, paleolimnology and ostracode fauna of kettles on the Illinoian till plain, Illinois, U.S.A
… intervals were investigated from fossiliferous successions in four breached kettle basins in south-central Illinois. The thickest measured successions of lacustrine/paludal sediment per basin include 16.4 m (Raymond Basin), 9.0 m (Bald Knob Basin), 7.0 m (Pittsburg Basin) and 4.3 m (Hopwood …

Reinterpreting vintage geophysical data from the Algoa and Gamtoos Basins, South Africa: an integrated sequence stratigraphic framework since the middle Mesozoic
… with how genetically related geological successions are deposited in time and space. This requires the integration of diverse types of datasets (drill core, outcrop, wireline, reflection seismic surveys, etc.) to build robust depositional models, the cornerstones of stratigraphic …

Facies and provenance analysis of the Midcontinent Rift System (MRS) in Kansas
… depths between 2846 and 11300 ft, comprises two successions. The lower one (11300-7429 ft) is dominated by clastic sediments and the upper one (7429-2846 ft) mainly by volcanic rocks, which suggests a radical change during rift evolution. This study is aimed at describing the sedimentary …

PALAEOECOLOGY, PALAEOENVIRONMENTAL ANALYSIS AND THEIR APPLICATION TO SEQUENCE STRATIGRAPHY: LOWER CRETACEOUS, LUSITANIAN BASIN, PORTUGAL
… palaeoecological study of three Lower Cretaceous successions (at Ericeira, Cascais, Cabo Espichel) from the southern part of the Lusitanian Basin, Portugal, provides a basis for this study. This palaeoecological analysis allowed the construction of a detailed picture of the effects of relative …

Tidal sedimentation in the mid-Pennsylvanian Breathitt Group, eastern Kentucky
… sedimentary structures, trace fossils, vertical successions of facies, and sediment body geometries suggest that these sediments were deposited in a delta-front/distributary-mouth-bar setting. Within the study area, the Magoffin Member ranges in thickness from 20 to 40 m. Where thickest, the …

Geology of Sub-Salt Carbonate Rocks in the Rozhkovsky Structure, Northern Precaspian Basin, Kazakhstan: Implications for the Formation of Carbonate Reservoir in a Relatively Closed Diagenetic System
Sub-salt carbonate successions in the Precaspian Basin host several world-famous oil/gas fields along the basin margin. The Early Carboniferous Sub-salt carbonate rocks are associated with the Rozhkovsky structure near the northern margin of the Precaspian Basin. These carbonate successions are …

TO SUCCEED IN SUCCESSIONS:FAMILY SUCCESSION AND FIRM BEHAVIOR IN CHINESE FAMILY FIRMS
In family firms, CEO successions are key events for firms’ sustainable development, and different types of successors may influence firm behaviors in significantly different ways. To respond to the mixed results of extant studies and unveil the underlying effects, this study adopted a …
