Abstract Pressure reduction following uplift may lead to dissociation of gas hydrates. The dynamics hydrate in such settings, however, are poorly understood. We used TOUGH+HYDRATE investigate the response hydrates an 0.009 myr $$^{-1}$$ - 1 </mml...
Introduction: The Kentland impact structure located in northwestern Indiana (N 40° 45’ W 87° 24’) represents the remains of an ~13km diameter complex crater. Ordovician-Devonian strata have been uplifted ~600 m to the surface following impact and subsequently exposed by local quarrying operations. Large megablocks of carbonates, sandstones, and shales have been uplifted along thrust faults to c...
Highlights • New data reveal for the first time a history of the last ∼33.7 ky of uplift of Samosir. • Minimum uplift rates were high (4.9 cm/year) for the first 11.2 ky but diminished after that to <1 cm/year for the last 22.5 ky. • Numerical modeling suggests that rebound of remnant magma augmented by deep recharge appears to be the most likely driver for uplift. • Detumescence makes a neglig...
The metabasite rocks from north of Shahrekord, which is a part of structural zone of Sanandaj-Sirjan, are undergone medium temperature – high pressure metamorphism (eclogite facies). These rocks then were subjected to a retrograde metamorphism (amphibolite facies). A distinct compositional zoning is preserved in fresh garnets which are formed during eclogite facies. The compositional or growth ...
Uplift modeling is a machine learning technique that aims to model treatment effects heterogeneity. It has been used in business and health sectors to predict the effect of a specific action on a given individual. Despite its advantages, uplift models show high sensitivity to noise and disturbance, which leads to unreliable results. In this paper we show different approaches to address the prob...
Original scientific paper In this paper, based on the overlapping deformation mode of load transfer law of uplift belled pile, and the theory of elastic mechanics, the elastic-plastic analytical solutions of uplift belled pile were derived, and the nonlinear elastic-plastic deformation analysis method was established, which made the deformation analysis theory of uplift belled pile more reasona...
We develop a model of an ice shelf-ice stream system as a viscoelastic beam partially supported by an elastic foundation. When bedrock near the grounding line acts as a fulcrum, leverage from the ice shelf dropping at low tide can cause significant ð 1 cmÞ uplift in the first few kilometers of grounded ice. This uplift and the corresponding depression at high tide lead to basal pressure variati...
چکیده: پرش یا جهش هیدرولیکی، از نوع جریان های متغیر سریع است و عبارت است از پدیده ای که طی آن جریان از حالت فوق بحرانی به حالت زیر بحرانی تبدیل می شود. مهم ترین کاربردهای پرش هیدرولیکی عبارتند از: کاهش انرژی آب در جریان از روی سدها، سرریزها و دیگر سازه های هیدرولیکی و نهایتاً محافظت قسمت های پایین دست.2- ترمیم و افزایش سطح آب در کانال ها به منظور پخش آب و همچنین کاهش فشار بالا برنده(uplift pr...
The South Atlantic region displays (1) a topographic gradient across the basin, with Africa elevated relative to South America, (2) a bimodal spreading history with fast spreading rates in Late Cretaceous and Eo-Oligocene, and (3) episodic regional uplift events in the adjacent continents concentrated in Late Cretaceous and Oligocene. Here we show that these observations can be linked by dynami...
