This book has been written in response to the rapid expansion and diversification of sedimentology during last 30 years. We believe that a critical synthesis this field is matter importance urgency. The study involves dynamic interplay with many other branches geology. Its tools range from those used measure submicroscopic ones involving use radar, reflection seismograph, Earth satellites. In introduction Part I we define wide scope sedimentology, as see it, which may be broader than some...
ABSTRACT Cores of shoreface sediments off Fire Island, Long New York, in water depths ranging between 5 and 21 m, contain a distinctive three-part sequence; from base upward consisting of: (a) basal lag, up to 50 cm thick, containing coarse gravel; (b) finely laminated sand 2 m having median diameters 0.210 0.125 ram, (c) burrow-mottled coarser size than unit (b), 30 thick. The boundaries (a), are sharp. relatively coarser, mottled composing the upper part this sequence results processes...
ABSTRACT Tidal inlets, narrow, comparatively deep gaps between barrier islands, are channels through which tidal currents flow vigorously as the water enters and leaves backbarrier lagoons, bays, intertidal flats marshes. Many geologists have compared inlets to river speculated that if an inlet shifts laterally, it should deposit a distinctive sequence of sediments, analogous point‐bar left by meandering stream channel. Fire Island Inlet, located 56 km east New York City, has migrated WSW at...

Abstract. The San Joaquin Valley (SJV) experiences some of the worst ozone air quality in US, frequently exceeding California 8 h standard 70.4 ppb. To improve our understanding trends number violations SJV, we analyze observed relationships between organic reactivity, nitrogen oxides (NOx), and daily maximum temperature southern SJV using measurements made as part at Nexus Air Quality Climate Change 2010 (CalNex-SJV). We find daytime speciated reactivity with respect to OH during CalNex-SJV...

Abstract. A relaxed eddy accumulation (REA) system combined with a nitrous acid (HONO) analyzer was developed to measure atmospheric HONO vertical fluxes. The consists of three major components: (1) fast-response sonic anemometer measuring both wind velocity and air temperature, (2) controlling unit separating motions into updraft downdraft samplers by the sign velocity, (3) highly sensitive based on aqueous long path absorption photometry that measures concentrations in updrafts downdrafts....
Abstract Measurements of HONO (g) and particulate nitrite (NO 2 − (p) ) were made with a modified Ambient Ion Monitor–Ion Chromatography (AIM‐IC) instrument during California at the Nexus Air Quality Climate 2010 in Bakersfield, CA (CalNex‐San Joaquin Valley (SJV)). Observations gas matter (PM 2.5 water‐soluble composition showed accumulation both species night, followed by loss next day. Intercomparison Stripping Coil‐UV/Vis Absorption Photometer (SC‐AP) demonstrated excellent agreement...
The Upper Triassic rocks of the New York-New Jersey-Pennsylvania and Connecticut Valley belts, generally considered to be deposits isolated basins, are inferred represent remnants filling an elongate rift valley that was 50 70 mi wide. In addition, stratigraphic thickness is hold approximately 30,000 ft. If these 2 conclusions correct, then Late tectonic history considerably more complex than previously thought can subdivided into 4 episodes. Episode 1: Initial graben subsidence without...

ABSTRACT Three lines of evidence based on data from more than 400 boreholes and vibrocores have been used to reconstruct the evolution barrier islands during Holocene transgression in southern Long Island, New York: (1) transgressive stratigraphic sequence behind present barriers, (2) patterns inner shelf, (3) morphology now‐buried late Pleistocene coastal features. The extensive preservation backbarrier sediments, radiocarbon dated between 7000 8000 yr BP, shelf Island suggests that...

ABSTRACT Micritic envelopes are commonly believed to develop from the lime‐mud infillings of circumferential perforations made in skeletal particles by algae. Because “algae” usually taken mean photosynthetic algae, corollary has been proposed that micritic would not appear on carbonate originating waters too deep for active growth Extensions this “photosynthetic‐algae‐only” origin implies that: ( 1 ) disappearance with depth could mark a useful paleobathymetric datum; and 2 preservation...
"Sedimentary structures and current-direction phenomena of the Kulm (lower Carboniferous) Floezleeres (upper graywackes eastern Rhenish Schiefergebirge (Sauerland) Oberharz areas, central Germany, have been examined in reconnaissance. These rocks are interpreted as deposits made by turbidity currents a relatively deep marine trough whose deepest portion migrated slowly northwestward across geosynclinal tract."
ABSTRACT The Pleasantview sandstone is a typical Pennsylvanian cyclothem in western Illinois exhibiting both channel and non-channel phases. In order to describe the interpret sediment transport direction environmental conditions existing at time of deposition, an investigation was made texture, composition, depositional structure, cross-bedding, dimensional fabric. Results this study indicate that subgraywacke which deposited north northwest direction. It concluded process cut large degree...

ABSTRACT Primary sedimentary structures can be used to infer conditions of flow which prevailed within fluid currents deposited the sediment. Three particularly important conclusions about drawn from primary structures: 1) The mechanisms suspension and traction, as defined by G. K. Gilbert in 1914, are fundamentally different, recognized different gross they produce sediments, effects brought distinctive paths followed particles move under influence each mechanism; 2) grain-to-grain...
