Estimation of the Total and Active Microbial Biomasses in Buried Subkurgan Paleosoils of Different Age

Microbiology, 2004
Microorganisms that were isolated from steppe soils buried below kurgans from 5800 to 750 years ago were analyzed for the completeness of isolation, total biomass (the sum of glucose-reactivated and resting microbial cells), and active biomass (metabolically active cells).

The Mechanisms and Time Factor of the Enzyme Structure of a Paleosoil

Biophysics, 2017
The data on the enzyme activity of paleosoils of archaeological sites are given. It is shown that the activity of phosphatases and urease in soils of ancient settlements is significantly higher than in modern soils: 1.5–2.0 times for urease and 7–15 times for phosphatase in some cultural layers of the Bronze Age.

Recognition And Significance Of Paleosoil Zones In A Heavy Oil Development Program

SPE International Thermal Operations and Heavy Oil Symposium and Western Regional Meeting, 2004
Abstract Several types of ancient soil zones are present in the reservoirs of the Hamaca Development Area, Orinoco Heavy Oil Belt of Venezuela. It is important to recognize these paleosoils when drilling production wells and when constructing reservoir simulation models. The major reservoir sands were deposited in fluvial and fluviotidal

DATABASE OF PALEOSOIL RESEARCH OF THE HOLOCENE WITHIN THE PLAINS OF UKRAINE ON THE BASIS OF GIS TECHNOLOGY

Ukrainian Geographical Journal, 2022
Today, the study of the development of Holocene nature and its individual components within the territory of Ukraine is quite active. The research results are reflected in dissertations and monographs as well as in numerous publications. But there is no separate generalizing scientific work linking all the available information. The aim of our work was

Multidisciplinary characterization of the “Ghiara” volcanic paleosoil (Mt. Etna volcano, Italy): Petrologic characters and genetic model

Lithos, 2022
The large expanses of lava field and soils spread out around Mt. Etna volcano (Italy), make unique the landscape of the whole area. In this work, we investigated a sample set of a peculiar aggregate locally named with the term "Ghiara" collected in different outcrops of Mt. Etna volcano southern flank.

A revision concerning the paleoenvironmental and paleoclimatic significance of the paleosoils

2007
The majority of paleosols are described from continental deposits, most commonly from alluvial strata. In these continental records to much little is revealed of conditions between events of sedimentation. In alluvial sedimentary environments, a record of these conditions is not lost and gone forever. They may be interpreted from fossil soils formed on
