Using X-ray fluorescence spectrometry major and trace elements have been estimated over a larhe variety of manganese nodules and crusts from th Pacific and the Indian Ocean. Of...

Mn, Fe, Ca, Co, Ni, Cu, Zn, Cd, Sn, Tl, Pb and Bi have been estimated in thirty-two nodules from the Pacific, Atlantic and Indian oceans. Various features about the composition...

Using spectrochemical techniques Fe, Si, Mg, Co, Ni, Cu, V, Mo, Ti and Tl have been estimated in nineteen manganese nodules, eight from the Atlantic ocean, seven from the...

In an earlier paper by two of the authors the conclusion was reached that the 33 recognized species of oxides of Mn could be separated into 3 groups: 1) those which appeared to...

This data set presents 14 bulk sample-based X-ray Fluorescence (XRF) measurements. For XRF sample preparation freeze-dried sediments (8 g) were seaved (2mm) to discard the...

High-resolution geochemical analysis of a 6-m-long sediment core from Zoñar Lake, southernSpain, provides a detailed characterisation of major changes in lake and watershed...

Trace element contents in microg/g measured on the <2 microns, 2-20 microns size fractions and bulk samples from LGM European loess sequences. Samples were crushed in an...

Several sites around Itasca State Park that are potentially representative of input sources to Deming Lake were sampled in August 2023. Water from a bog on the southeast margin...

A core of ice from the center of the lake was obtained in March 2023 using a Kovacs Mark V coring system. The core barrel extracts a 14 cm diameter ice core and returned a ~40...

Sediment samples from the lake bottom were collected from the boat in May 2022. Ten samples capturing a few centimeters depth of the upper sediment layer were collected from...

Sampling and in situ sensor analysis was conducted from an anchored boat at the deepest location of the lake, approximately 20 m water depth, in May 2022, August 2022, March...

This table comprises whole rock geochemistry of the basement rocks (Sybella Granite, Proterozoic Schists and McNamarra Group metasediments) that underlie the Georgina Basin...
