The Early Devonian Rhynie hot spring system is the oldest known and is of the low sulphidation type. It extends for at least 1.5 km along a major fault zone defining the western margin of an outlier of fluvial and lacustrine sediments, plant-bearing sinters and andesitic lavas. The age of sedimentation and hydrothermal activity has been determined by palynological (Pragian) and radio-metric (396 ± 12 Ma) techniques. The outlier is a half graben with a complex stepped western margin. The… 
Fluids and hydrothermal alteration assemblages in a Devonian gold-bearing hot-spring system, Rhynie, Scotland
ABSTRACT Hydrothermal alteration at Rhynie, Aberdeenshire, Scotland, is concentrated along a fault zone, which juxtaposes surface deposits and the mineralised feeder zone to the Rhynie hotspring
Geological setting of the Early Devonian Rhynie cherts, Aberdeenshire, Scotland: an early terrestrial hot spring system
Abstract: The drilling of nine cored boreholes, including a deep hole (233 m) to a gabbroic basement, in the vicinity of the Rhynie chert locality has resulted in a major revision of the structure
Characteristics and variations of sinters in the Coromandel Volcanic Zone: application to epithermal exploration
ABSTRACT The Hauraki Goldfield of the Coromandel Volcanic Zone, North Island, New Zealand, hosts up to 19 known siliceous hot spring deposits, or sinters, some directly associated with Au–Ag ore
The geology of the northern half of the Rhynie Basin, Aberdeenshire, Scotland
ABSTRACT A new geological map of the Early Devonian Rhynie Basin has been produced by traditional methods supplemented by trenching to bedrock and a ground magnetic survey. This shows that the basin
Lithofacies and biofacies of mid-Paleozoic thermal spring deposits in the Drummond Basin, Queensland, Australia.
The Devonian to Carboniferous sinters of the Drummond Basin, Australia, are among the oldest well established examples of fossil subaerial hot springs and represent an untapped source of paleobiological information on the history of hydrothermal ecosystems.
The Kohuamuri siliceous sinter as a vector for epithermal mineralisation, Coromandel Volcanic Zone, New Zealand
The Kohuamuri siliceous sinter is the largest known fossil hot-spring system in the Hauraki Goldfield, a 200 × 40 km volcanic terrain with at least 50 adularia-illite epithermal deposits formed
The Case for Ancient Hot Springs in Gusev Crater, Mars
New and existing observations of the Home Plate region with observations from field and laboratory work demonstrate that a volcanic hydrothermal system manifesting both hot spring/geyser and fumarolic activity best explains the opaline silica rocks and proximal S-rich materials, respectively.
Jurassic hot-spring activity in a fluvial setting at La Marciana, Patagonia, Argentina
Abstract Silicified rocks at La Marciana farm, Deseado Massif, Argentinean Patagonia, represent an ancient hot-spring discharging into an active fluvial setting. Their fortuitous burial–erosion


Stratigraphy and sedimentology of the Devonian Rhynie chert locality
Synopsis Recent drilling in the vicinity of the Rhynie chert locality in the Rhynie outlier of Lower Old Red Sandstone allows a local stratigraphic succession to be established. A basal lithic
The Rotokawa geothermal system, New Zealand; an active epithermal gold-depositing environment
The Rotokawa geothermal system is less than 20,000 yrs old and is situated in a sequence of Pleistocene and Recent volcanic rocks and underlying Mesozoic graywacke basement in the Taupo volcanic
Paleozoic hot spring sinter in the Drummond Basin, Queensland, Australia
Sinter constructs terraced aprons around the hot spring discharge sites of many active, high-temperature (>150øC) geothermal systems, such as those at Steamboat Springs in Nevada, Yellowstone in
Epithermal sinters of Paleozoic age in north Queensland, Australia
Silica sinters deposited from hot springs have been found associated with volcanic rocks of Late Devonian to late Carboniferous age in north Queensland, Australia. These deposits have many features

Synopsis The Boganclogh intrusion, which appears to be a westerly extension of the Insch mass, is chemically and petrologically subdivided into three principal units which occupy roughly east-west
Depositional environment and preservation of biota in the Lower Devonian hot-springs of Rhynie, Aberdeenshire, Scotland
The Lower Devonian plant- and arthropod-bearing cherts of the Rhynie area of Aberdeenshire, NE Scotland, were deposited from silica-rich waters emanating from the hot-springs of a precious-metal (Au)
