Mapping Hot Spring Deposits with Aviris at Steamboat Springs, Nevada
1.0 INTRODUCTION Active and fossil hot springs systems occur worldwide, and share many common characteristics that indicate similar genetic histories (White 1955; Waring 1965; Rhinehart 1980; White 1981; Bowen 1989). This research studies the occurrence and characteristics of hot springs at Steamboat Springs, Nevada using Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data. Both highan...
متن کاملEarliest signs of life on land preserved in ca. 3.5 Ga hot spring deposits
The ca. 3.48 Ga Dresser Formation, Pilbara Craton, Western Australia, is well known for hosting some of Earth's earliest convincing evidence of life (stromatolites, fractionated sulfur/carbon isotopes, microfossils) within a dynamic, low-eruptive volcanic caldera affected by voluminous hydrothermal fluid circulation. However, missing from the caldera model were surface manifestations of the vol...
متن کاملHot and Cold Spring Deposits as a Source of Palaeo-fluid Samples on Mars
Introduction: Fluid inclusions are micron-scale volumes of fluid entrapped during the precipitation of minerals. Fluids are entrapped during primary mineral growth, and during healing of later fractures. The water in fluid inclusions in minerals precipitated in the upper crust of Mars contains a record of the ambient environment during precipitation. This includes data on fluid temperature and ...

متن کاملSilica deposits on Mars with features resembling hot spring biosignatures at El Tatio in Chile
The Mars rover Spirit encountered outcrops and regolith composed of opaline silica (amorphous SiO2·nH2O) in an ancient volcanic hydrothermal setting in Gusev crater. An origin via either fumarole-related acid-sulfate leaching or precipitation from hot spring fluids was suggested previously. However, the potential significance of the characteristic nodular and mm-scale digitate opaline silica st...
