The disarticulation sequence of human bodies

Our understanding of the fluvial taphonomic processes is still in its infancy;

In waterstreams and rivers it is still poorly researched.

Historically, research concerning the transport of remains in rivers has been performed in the fields of paleontology and archaeology,

Bodies can be transported 100's of miles within a few days or as long as several months in large river systems.

Decomposition rates slow down in the water, primarily due to cooler temperatures and the anaerobic environment.

However, once a body is removed from the water, putrefaction will likely be accelerated.

Corpses that travel downstream in a river don’t typically disarticulate quickly, compared to when they’re on dry land.

The decay of tissues in rivers proceeds differently than decay in lakes and ponds, since the decay products are swept downstream, the biota is different in flowing water.

Wrinkling of the skin and eventual sloughing of skin is where this process begins.

Larger bones (length, volume, area, or diameter) tend to travel downstream slower than smaller ones.

A 2008 study on two human bodies recovered following aircraft accidents found one body off Sicily to be partially skeletonized after 34 days and a second body off of Namibia to be completely skeletonized after three months.

However rapid skeletonization of remains may occur in bodies of water in tropical areas, due to water temperature and carnivorous fish species.

Transport potential means the ability of a bone to travel long distances downstream.

There are large variations in transport potentials, according to bone size, smaller bones often move less than larger bones, and vice versa.

Both shape and orientation affect transportability, flat bones tend to lay flat on the river bed and not move.

Elongated bones tend to orient parallel or perpendicular to flow, with parallel orientation most common when water depths greatly exceed the height of a bone.

Often when searching, it is most common to find larger bones and miss other smaller skeletal remains.

When searching, it is recommended to look on the upstream sides of obstructions , in eddies behind obstructions , on bars (of any kind: lateral, point, median, etc.; and to focus the search on the same side of the river as the body/parts entered (if known)).

All locations with drops in flow velocity should be searched, including banks, the upstream and lateral edges of deeper p

For context - it's been shown that the subsurface microbial communities differ based on location along a subduction zone arc. This seems to be due to dissolved carbon. Would there be differences in the general chemistry and DC contents between different subduction zones/volcanic arcs?

Dabakala Concession Demonstrates High Grade Geochemical Anomaly and Exploration Update

Kodal Minerals, the mineral exploration and development company focused on the Bougouni Lithium Project and its gold assets in West Africa, is pleased to provide an update on the gold exploration programme in Côte d'Ivoire including the return of continued high-grade surface geochemical results from the Dabakala Concession ('Dabakala') in central Côte d'Ivoire.

Highlights

Dabakala Concession

· Geochemical sampling continues to return high grade surface samples at new discovery zone.

o New assay results up to 1.97g/t gold

· Infill sampling has confirmed continuity of high grade gold anomalism extending for over 11km and surface width up to 3km.

o Multiple trends are interpreted relating to geological structures and contacts.

· Field reconnaissance and mapping of artisanal working has been completed.

o Check sampling confirmed previous high grade surface samples with check samples of an initial 2.1g/t sample returning values of 4.2g/t gold and 3.5g/t gold

· Aircore drilling rig retained to undertake first pass testing of this high priority area with drilling expected to commence from 21 June 2021.

Highlights

Nielle Concession and Fatou Prospect

· Aircore and reverse circulation ('RC') drilling completed at the Nielle Concession in Côte d'Ivoire with all samples dispatched to the laboratory for gold analysis.

· RC drill rig secured for the Fatou Prospect in Mali with drilling expected to commence before the end of June 2021, allowing for initial confirmation drilling of this previously reported resource prior to the annual rainy season.

Bernard Aylward, CEO of Kodal Minerals, commented: "We are making great progress with our gold exploration programmes in Côte d'Ivoire. The wide-spread, consistent surface gold anomalism at Dabakala is an enticing prospect with multiple newly defined gold trends in a previously unexpl
