Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Apatite Fission Track Thermochronology of Granite from Duobaoshan Porphyry Cu (Mo) Deposit, Northeast China: Implications for Cooling History and Ore Preservation

Geofluids, 2022
The Duobaoshan Cu (Mo) deposit is one of the oldest super large porphyry deposits in the eastern part of the Central Asian orogenic belt. Although ore-forming processes have been extensively concerned, the post-mineralization ore preservation state was ...

Petrogenesis and metallogenic implications of the Miocene granite porphyry in the Jiama Cu-polymetallic deposit, Gangdese belt, South Tibet

, 2022
Geochronology, geochemical and isotopic studies were carried out on granite porphyry from the Jiama Cupolymetallic deposit, Gangdese porphyry copper deposit belt, to constrain the genesis and metallogenic potential. LA-ICP-MS zircon U-Pb dating indicates

A Machine Learning Zircon Trace Element Tool to Predict Porphyry Deposit Type and Resource Size

Journal of Geophysical Research: Machine Learning and Computation
Porphyry deposits are primarily known for their association with base metals like copper and to some extent molybdenum and gold. Here we present machine learning models, based on zircon composition, that provide quantitative distinction between different

Comparisons Ancient and Modern: Was Cyril of Alexandria a Good Reader of Paul?

International Journal of Systematic Theology, EarlyView.
Abstract Cyril of Alexandria is the final stop on Michael Magree's analysis of the patristic interpretation of Pauline kenosis, serving as the culmination of the historical arc he surveys. Although Magree is careful to avoid overtly judging the success of various interpreters as readers of the Apostle, it is clear that he finds Cyril's appropriation of

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...
