Abstract:

Abstract— Throughout millions of years of geological history (in the Phanerozoic), the coevolution of all living organisms took place in a fierce competition for resources and opportunities for the maximum reproduction. Due to the geochemical heterogeneity of the primary (pre-Quaternary) biosphere, this resulted in a self-regulating system of ecological niches, within which all local biocenoses and their animal and plant species were maximally adapted to the parameters of the habitat. However, with the emergence of reason, the situation changed fundamentally. Human beings became the dominant s

In the quest to use modern analogues to understand clay mineral distribution patterns to better predict clay mineral occurrence in ancient and deeply buried sandstones, it has been necessary to define palaeo sub-environments from cores through modern sediment successions.

Abstract:

In this study, the geochemical analysis of the subgrade at different locations of Ilaro-Papalanto highway was conducted using Atomic Absorption Spectrometry (AAS) and X-Ray Diffractometry (XRD). The predominant oxides present in both soil samples are Silicon Oxide (40% - 45%) and Aluminium Oxide (31% - 34%), and the average silica content of Ilaro and Papalanto are 45.71% and 40.71% respectively, which implies that Ilaro soil sample is more chemically inert and structurally stable than Papalanto soil samples. The average sesquioxide content of Papalanto (36.27%) is higher than that of Ilaro (3

Abstract:

Trace metals and metalloids are a common and persistent form of riverine (river) contamination and are derived from a wide variety of sources, including mining and milling operations, industrial activities, urban runoff, agricultural chemicals, and atmospheric pollution, among a host of others. Documentation of trace metal sources and dispersal pathways in riverine ecosystems is essential to mitigate their potentially harmful effects to human and ecosystem health and is often required from a legal (environmental forensic) perspective to assess liability for the costs of remediation.
