Notes

General Note:
Development of the Nowranie Caves includes both phreatic and vadoese components, with prominent influences on cave geomorphology exerted by joints, bedding the past changes in watertable levels. Active circulation is occurring within a phreatic conduit at moderate depth (22-30 m) below the level of the present watertable. Slugs of flood water can penetrate well into the flooded section of the cave, and it appears that dissolutional enlargement of the conduit may be occurring under present conditions. Speleogensis in Nowranie Caves incorporates deeper phreatic processes in addition to shallow phreatic (i.e. watertables) processes. A series of three fossil, of occasionally re-flooded, phreatic horizontal levels in the Nowranie Caves correspond with similar levels in other Camooweal caves, and reflect a regional pattern and multi stage history watertable changes linked with cave development. The stacked series of cave levels may reflect episodic uplift, wetter climate episodes, or a combination of both - possibly dating form early to mid Tertiary times. Caves and dolines are the major points for groundwater recharge in the Camooweal area, and these are susceptible points for injection of contaminants into the groundwater system. A climatic and distributional relict, and locally endemic, fauna is present in the groundwater. The Nowranie Caves, and Camooweal area generally, has conservation significance as a karst hydrogeological and ecological system that has preserved a history of regional landscape and faunal evolution in northern Australia during the Quatermary. -- Authors

Description
Development of the
Nowranie Caves includes both phreatic and vadoese components,
with prominent influences on cave geomorphology exerted by
joints, bedding the past changes in watertable levels. Active
circulation is occurring within a phreatic conduit at moderate
depth (22-30 m) below the level of the present watertable.
Slugs of flood water can penetrate well into the flooded
section of the cave, and it appears that dissolutional
enlargement of the conduit may be occurring under present
conditions. Speleogensis in Nowranie Caves incorporates deeper
phreatic processes in addition to shallow phreatic (i.e.
watertables) processes. A series of three fossil, of
occasionally re-flooded, phreatic horizontal levels in the
Nowranie Caves correspond with similar levels in other
Camooweal caves, and reflect a regional pattern and multi stage
history watertable changes linked with cave development. The
stacked series of cave levels may reflect episodic uplift,
wetter climate episodes, or a combination of both possibly
dating form early to mid Tertiary times. Caves and dolines are
the major points for groundwater recharge in the Camooweal
area, and these are susceptible points for injection of
contaminants into the groundwater system. A climatic and
distributional relict, and locally endemic, fauna is present in
the groundwater. The Nowranie Caves, and Camooweal area
generally, has conservation significance as a karst
hydrogeological and ecological system that has preserved a
history of regional landscape and faunal evolution in northern
Australia during the Quatermary. --
