Deconvolving the Effects of Fluvial Transit and Storage on Preservation of Sedimentary Source Signals Using Heavy Minerals and Terrestrial Biomarkers

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
Sediment pathways from source to sink: Organic and clastic sediments are stored and transformed during floodplain transport and deposition, with transport modes shaping signal transmission and sediment alteration. ABSTRACT Analysis of naturally occurring markers of environmental signals, or proxy analysis, in sedimentary records can yield valuable ...

Geologic Guide for the Northern Part of the Peninsular Range Province, Southern California [PDF]

open access: yes, 1954
This geologic guide deals with parts of Los Angeles, San Bernardino, Riverside, and San Diego Counties, in southern California, and in effect is a sampling of the geology and mineral deposits in the northern part of the Peninsular Range province.

Trained Immunity and Cardiovascular Risk: An Immunological Perspective

open access: yesImmunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Systemic inflammation is a key driver of atherogenesis and its complications. While anti‐inflammatory therapies targeting pathways such as IL‐1β and IL‐6 have shown promise in established atherosclerotic cardiovascular disease (ASCVD), potential systemic effects raise concerns about immune suppression and infection, underscoring the need for ...

Pegmatites of Southern California [PDF]

open access: yes, 1954
For many years the southern California region has attracted the attention of geologists interested in pegmatites and pegmatite deposits, largely because of the well-known gem and lithium occurrences in San Diego and Riverside Counties. These world-famous

Geochemistry and U–Pb Zircon Geochronology of Granite at the Pilok Sn–W Deposit, Thailand: Implications for Late Triassic Tin Metallogenesis

open access: yesResource Geology, Volume 76, Issue 1, January/December 2026.
Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

Geology of a Part of the Panamint Range, California [PDF]

open access: yes, 1932
The Panamint Range is a tilted fault-block, uplifted probably in Tertiary time and rejuvenated by very complex recent faulting on the west. This great block is approximately 100 miles long, but the reconnaissance geologic map covers only a tract in the ...

Tourmaline-quartz-cassiterite mineralization of the Land's End Granite at Nanjizal, west Cornwall [PDF]

open access: yes, 2013
Nanjizal is one of the few locations in the southern segment of the Land's End Granite (Early Permian) where magmatic-hydrothermal tin mineralization has been worked. Three principal mineralization episodes are recognized.
