... on the specimen DAK-407/2 and better matches the proportions of a complex with a free parhypural. An assessment of the morphology of the anterior part of this bone will have to await the discovery of more complete material. The specimen DAK-407/2 is interpreted as an indeterminate Scombroidei based on the fusion...

... ). The pressure of formation of clinopyroxenes of the Dak Nong megacryst assemblage was determined using the clinopyroxene barometer ( Nimis, 1999 ) based on the relationship between pressure and the volumes of the unit cell and polyhedron M1 in the mineral structure. These pressures are 14–17 kbar...

... hosted in the basalts of the Dak Nong province from southern Vietnam from the petrographic, geochemical and O-isotopic study of the sapphires and their host rocks. New oxygen isotopic data on sapphire and ruby originating from different kinds of protolith possibly derived from the mantle or the lower...

... discontinuously within the valleys of Dak Koi and Dak Bla rivers in the Kon Ray area ( Fig. 2 ). These formations principally comprise of coarse-grained debris with poor roundness such as boulders, chips, grit, and less pebbles, weakly bound together by smaller materials like sand, clay. The observed thickness...

... data from Google Earth Engine, such as Landsat and Sentinel-2 images. More specifically, CoastSat uses a neural network-based classification method to identify the shoreline through a series of image classification and border segmentation steps. The initial phase involves classifying the pixels...

... success ratio was 67%, based on 72 wells successfully completed for production, out of 120 development wells drilled. Of all the wells drilled, 45% produced oil. Comparable figures for 1962 show 235 wells drilled: 4 wildcats produced oil; 91 were dry (4.4% wildcat success ratio); 99 development wells...

... belonging to ‘C.’ koerti were found in situ inside the hard bone bed (as DAK.4; Fig. 3 i) at the base of B1, and their state of preservation is clearly different from all the other taxa, showing a worn patina, blunted cutting edges and sometimes many marks that suggest a reworking from older deposits...

...Wayne A. Pettyjohn The middle part of the Fairpoint Member is composed dominantly of compact, uncemented silt and fine- to medium-grained dirty sand, and ranges in thickness from 128 to 162 ft. These beds are highly cross-bedded, and cut-and-fill features are common. At the base in most areas...

... areas in the southernmost regions of the basin ( Fig. 4 ). To explore thermal histories for these regions, we ran inverse models based on ZHe and AHe data only. From the Dease Lake area we modeled 16RGI45307, a Laberge Group sample in the footwall of the King Salmon thrust/hanging wall of the Kehlechoa...

...John F. Halpenny; Dak M. Darbha Abstract Airborne gravity measurements were made over Lake Ontario in March 1991 to establish the feasibility of using a small survey aircraft for rapid and economical gravity surveys. A LaCoste and Romberg linear dynamic gravity meter, used with a PC lap-top based...

... by broad folds and fewer faults in the southern region. The present paper uses the three fold classification of the Siwaliks given by the O.N.G.C. workers (see Sahni and Mathur, 1964). Though this classification is based on heavy mineral assemblages, the three sub-divisions of the Siwaliks viz., Lower...

... than the above two. The two suggested river patterns are based on the distribution of the distributary sandstone bodies as interpreted from subsurface data. The relative ages are quite hypothetical, but again the northwest-trending delta lobe seems to have been built out the farthest distance...

... dolomite, with a pay thickness ranging up to 50 ft, produces 40°–47° API oil in these seven fields. Data from closely spaced wells amply demonstrate that structural closure is important as the basic trapping mechanism for Nisku oil. Various interpretations have been given regarding the influence which...

... Potsdam datum (Chugh. 1977). A known gravity station at Dak Banglow (Rest House) of Dharamsala has been used as the base station. Two other known gravity stations at Palampur and Kangra established in 1988 by SOl with respect to national grid were reoccupied in 1989 and 1990. All gravity values...

...H. J. Meyer; H. W. McGee ABSTRACT Definite “hot spots” or positive geothermal anomalies are associated with 15 of 22 Rocky Mountain oil and gas fields examined in Montana, North Dakota, Wyoming, Utah, Colorado, and New Mexico. Of the remaining 7 fields, 5 have poor to sparse data, and the other 2...

..., which is compatible with magma formation within and from the lower continental crust, triggered by injection of basaltic magmas from the mantle, a generally accepted scenario for the formation of a calc-alkaline series (e.g., DePaolo et al. 1991 ). Evidently, this hypothesis is based on a limited data...

...James R. Shouldice ABSTRACT Oil wells drilled on Bowes Dome have provided data to help interpret some rather unusual structural features noted in this area. Bowes Dome is a gentle, symmetrical structure several miles in diameter with closure of more than 100 feet. A great many normal faults cut...

The spectra are based on 15 sec of S -wave record for the earthquake recordings. For the SHIPS data, record lengths of 10 and 15 sec were used...
