cheshmeh-konan area is located ~15 km northwest of tasuj, east-azarbaidjan province. the most important lithologic units of the area are red sandstones, green-gray sandstones, shale, and marl (miocene). based on field evidence and petrographical investigations, the host sediments were deposited in a peritidal setting associated with a sabkha-type environment. copper mineralization in the area o...
Tropical forests store large amounts of carbon in tree biomass, although the environmental controls on forest carbon stocks remain poorly resolved. Emerging airborne remote sensing techniques offer a powerful approach to understand how aboveground carbon density (ACD) varies across tropical landscapes. In this study, we evaluate the accuracy of the Carnegie Airborne Observatory (CAO) Light Dete...
Mines with exceptionally low-strength roof (UCS <3,500 psi and CMRR <40) are much more likely to struggle with roof falls than other mines. Weak roof is a particular problem for many room and pillar mines in the Midwestern and Northern Appalachian coal basins. Traditional roof support techniques are often not up to the challenge at these operations. This paper focuses on two mines, one operatin...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
In order to study the micro genetic mechanism and main geological controlling factors of low resistivity reservoir in NgIII formation X oilfield Bohai sea China, clay mineral composition, irreducible water saturation, salinity conductive minerals were studied by using data core, cast thin section analysis, compared with normal reservoir. At same time, control effect sedimentary environment on w...
For over 50 years, cores recovered from ocean basins have generated fossil, lithologic, and chemical archives that revolutionized fields within the earth sciences. Although scientific drilling (SOD) data are openly available following each expedition, formats for these heterogeneous. Furthermore, lithological, chronological, paleobiological typically separated into different repositories, limit...
