Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

GOLD-POLYMETALLIC MINERALIZATION OF THE RIDDER-SOKOLNOYE DEPOSIT IN THE RUDNY ALTAI (EASTERN KAZAKHSTAN) [PDF]
Минералогия, 2018 New geochemical data on distribution of gold mineralization in the ore lode sections of the Ridder-Sokolnoye deposit, the largest in Rudny Altai, confirm the crossing style of gold-quartz veins and gold-bearing stockwork relative to the zonal bodies of ...

, 2008 The Karalar galena-barite deposits are typical examples of the carbonate-hosted barite-galena deposits widely occurring in the Central Tauride Belt. These deposits are located in Permian limestones as ore veins along fault zones that are discordant to ...

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Rethinking a positive‐sum game: US FDI location decisions in the presence of Chinese FDI
Global Strategy Journal, EarlyView.Abstract Research Summary This study examines how rising Chinese outbound foreign direct investment (OFDI) in third‐country markets shapes US MNEs' foreign direct investment location decisions amid escalating US–China geopolitical rivalry. US firms initially benefit from complementary co‐location dynamics, as Chinese OFDI—particularly in infrastructure—

Flexible List Coloring of Graphs With Maximum Average Degree Less Than 3
Journal of Graph Theory, EarlyView.ABSTRACT In the flexible list coloring problem, we consider a graph G $G$ and a color list assignment L $L$ on G $G$, as well as a subset U ⊆ V ( G ) $U\subseteq V(G)$ for which each u ∈ U $u\in U$ has a preferred color p ( u ) ∈ L ( u ) $p(u)\in L(u)$. Our goal is to find a proper L $L$‐coloring ϕ $\phi $ of G $G$ such that ϕ ( u ) = p ( u ) $\phi (u)=
