Diversity of Protists III01:27

Diversity of Protists III

1.2K
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Formation of Species

45.5K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Formation of Complex Ions

26.4K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Sulfur Assimilation01:20

Sulfur Assimilation

400
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...

Nuclear Transmutation03:20

Nuclear Transmutation

20.8K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

Area of Science:

  • * Geochemistry and Petrology
  • * Economic Geology
  • * Tectonics

Background:

  • * Giant gold deposits are linked to enriched crustal or mantle sources.
  • * Lithospheric processes controlling gold endowment in metallogenic provinces are not fully understood.
  • * Current models often focus on crustal enrichment mechanisms.

Purpose of the Study:

  • * To provide direct evidence of gold in the mantle source region.
  • * To elucidate the lithospheric-scale processes responsible for gold endowment.
  • * To link mantle enrichment to the formation of large auriferous provinces.

Main Methods:

  • * Geological mapping and geochemical analysis of mantle xenoliths.
  • * In-situ analysis of native gold within mantle rocks.
  • * Geochronological studies to constrain timing of mantle processes and magmatism.

Main Results:

  • * Direct evidence of native gold discovered in the mantle beneath the Deseado Massif, Patagonia.
  • * Mantle refertilisation by Early Jurassic plume-derived melts created a gold-rich mantle source.
  • * Interaction between this enriched mantle and Middle-Late Jurassic subduction fluids generated ore-forming magmas.

Conclusions:

  • * Mantle refertilisation is a critical factor in the formation of large metallogenic provinces.
  • * An enriched subcontinental lithospheric mantle can serve as the primary source for significant gold deposits.
  • * This finding challenges purely crust-centric models of gold endowment, proposing a dual mantle-crustal enrichment model.
