Thermal history modeling based on low-temperature thermochronological data is widely used in the study of geology. Despite its common applications, several problems remain easy to ignore yet should not be overlooked execution such models. This paper describes four key thermal modeling, namely, (1) best-fit best? (2) Is date constraint box a suitable constraint? (3) Does bimodal distribution apa...

Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...

Since the mid 1970s, Interior Alaska white spruce trees experienced markedly lower growth than during the 19th and early 20th centuries. This observation raises the question of forest persistence on certain sites of lowland central and eastern Alaska. We analyzed white spruce growth across a 36-site network (540 trees) on three major river floodplains in boreal Alaska along a longitudinal gradi...

Temperature cycling tests are standard industry practice for determining the thermomechanical fatigue life of solder joints. Industry-standard temperature pro¢les usually start from room temperature, then go to a high temperature, then to a cold temperature, and then back to room temperature. In addition, most of the time, the temperature pro¢le contains dwell times at the highest and lowest te...

High-precision calculations of a series of standard models of the internal structure of the Sun using diierent opacity tables are presented. The models are compared on the basis of two key parameters-helium abundance and speciic entropy in the convection zone. The eeect of opacity on these two parameters in the radiative interior of the Sun is studied. Comparison of standard models calculated u...

NASA’s Juno spacecraft will make microwave and gravity measurements of Jupiter. These can reveal information about the composition of Jupiter’s atmosphere and about the temperature and density structure below the visible clouds, which is in balance with the structure of the zonal winds. Here we show that there exist strong physical constraints on the structure of the off-equatorial deep zonal w...
