Quaternary lacustrine deposits exist within several valleys in the Valles caldera in northcentral New Mexico . These deposits contain potentially valuable paleoclimatic records . We report OSL ages for a section of unconsolidated Quaternary sediments exposed in the southwest part of Valle Toledo within Valles caldera . The sequence represents the transition over time from lacustrine to fluvial ...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

In the desert of Abarkoh Basin, Central Iran, the influence of playa-lake level fluctuations on recent sedimentation mode of a terminal ephemeral fluvial-fan system and adjacent lacustrine/aeolian sediments of a playa fringe environment has been investigated. The surface geomorphology-sedimentology and its relationship with shallow subsurface sediments along a >25 km transect, has been studied....

Lakeshore environments offer an excellent opportunity to explore how early humans adapted changing landscapes and environments. The Nihewan fluvio-lacustrine sequence in North China contains one of the densest concentrations Early Pleistocene Palaeolithic sites outside Africa. Among these, Cenjiawan site, dated at 1.1 Ma, draws attention due large number stone tool refits. We present here Cenji...

Lacustrine shale has garnered significant attention due to its resource potential. The Jurassic in the Sichuan Basin is an important target for lacustrine exploration China. However, previous studies have predominantly focused on Da’anzhai member of Ziliujing Formation, and little been paid other strata. This paper aims address this gap by investigating Dongyuemiao Basin. study systematically c...

The sandstone-hosted Beverley uranium deposit is located in terrestrial sediments in the Lake Frome basin in the North Flinders Ranges, South Australia. The deposit is 13 km from the U-rich Mesoproterozoic basement of the Mount Painter inlier, which is being uplifted 100 to 200 m above the basin by neotectonic activity that probably initiated in the early Pliocene. The mineralization was deposi...

Abstract Continental depositional environments preserve the majority of the macrofloral record since the advent of land-plant colonization in the mid-Paleozoic, and wetland representatives are encountered more commonly than those that grew under more seasonal conditions. It has been assumed that preservation potential and future recovery of plant debris are high once detritus is introduced into...

Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...

White Creek, Cripple Creek, Hayden Creek, Shadow Brook, and Mount Wellington watercourses constitute the northern watershed of Otsego Lake (Figure 1). Approximately 44% of the northern watershed is devoted to agricultural utilization (Harman et. al. 1997) and the potential for anthropogenically derived additions of total carbon (TC), total inorganic carbon (TIC/IC), and nitrogen affecting the l...
