  Connemara - Matabeleland North Province - 津巴布韦 - GeoSeven   (Site not responding. Last check: 2007-10-20)
Conamara (anglicised Connemara), which derives from Conmhaicne Mara (meaning: descendants of Con Mhac, of the sea), is a district in the west of Ireland comprising of a broad peninsula between Killary Harbour and Cuan Chill Chiaráin / Kilkieran Bay in the west of County Galway or south west Connacht.
Conamara lies in the territory of Iar Connacht "West Connacht", which is the portion of County Galway west of Lough Corrib and the portion of County Mayo in the barony of Ross.
Conamara is composed of the Catholic parishes of Carna, Clifden (Omey and Ballindoon), Ballynakill, Roundstone and Inishbofin.

 Conamara Chaos Information
The Conamara Chaos Zone is a region of chaotic terrain on Jupiter's moon Europa.
Conamara is a landscape produced by the melting of ice.
The region consists of plates of ice that have moved around and rotated.

 Chaos on Europa
Chaos areas seem to get smaller and sparcer the farther north they are in the northern hemisphere in the regions where we have adequate resolution for this mapping.
The relationships between chaos regions and larger, pre-existing ridge systems indicate that the crust around and under the ridges is generally more able to resist the chaos-forming process, although in some cases chaos appears to have broken out squarely on the site of ridges.
Much of the chaos area marked in green in our maps, which we interpret as being older than the fresh chaos marked in red, does show fine lineaments across its matrix, consistent with the idea that chaos erasure is carried out by fine scale fracture and ridge features.

 Europa
This melt could be delivered in the form of a rising liquid dike which spreads out near the surface into a sill, or could form within the ice shell if a rising diapir of warm ice impinges on a layer of salt-contaminated ice with a low melting temperature.
Topographic profiles of Conamara Chaos led Schenk and Pappalardo (2004) to conclude that the data are most consistent with diapir upwelling in a thick shell.
A wide range of models can account for chaos formation on Europa: melt-through, diapirism, and penetrating impacts could each generate the appropriate morphologies under proper conditions, and all are driven by plausible physical mechanisms.

 WHOI : People : Jason C. Goodman, Jason Goodman : Publications
Hydrothermal plumes may be responsible for transmitting radiogenic or tidally generated heat from Europa’s rocky interior through a liquid ocean to the base of its ice shell.
This process has been implicated in the formation of chaos regions and lenticulae by melting or exciting convection in the ice layer.
The observed movement of ice blocks in the Conamara Chaos region is unlikely to be driven by such weak flow.

The point is to move from Chaos to Lex.
The unknown compression process, from T1V1 to T2Vo, obviously was done both by applying work, to decrease the volume AND heat to increase the temperature (work doesn't show in the TS-diagram).

 CiteULike: Topographic variations in chaos on Europa: Implications for diapiric formation   (Site not responding. Last check: 2007-10-20)
Disrupted terrain, or chaos, on Europa, might have formed through melting of a floating ice shell from a subsurface ocean [Carr et al., 1998; Greenberg et al., 1999], or breakup by diapirs rising from the warm lower portion of the ice shell [Head and Pappalardo, 1999; Collins et al., 2000].
Vertical and horizontal scales of topographic doming in Conamara Chaos are consistent with a total ice shell thickness >15 km.
High-resolution stereo-controlled photoclinometric topography indicates that chaos topography, including the archetypal Conamara Chaos region, is uneven and commonly higher than surrounding plains by up to 250 m.

 p22b-11 in fm98   (Site not responding. Last check: 2007-10-20)
We define chaos as large regions typified by dislocated polygonal blocks similar in structure to surrounding lineated bright terrain, and intervening matrix material (subdivided into angular blocks, peaks, micro-blocks, and hummocky material) lying at a lower topographic elevation than the linear-textured blocks.
Movement of polygons appears to be inward from the chaos boundary (which is a prominent escarpment) and clockwise in the center.
Chaos formation at Conamara involves destruction of over half the pre-existing terrain and mobilization, translation, and rotation of the remaining polygonal blocks, implying elevated near-surface temperatures and a mobile substrate over lateral scales of ~100 km.

 Connemara at AllExperts
Conamara (anglicised Connemara), which derives from Conmhaicne Mara (meaning: descendants of Con Mhac, of the sea), is a district in the west of Ireland (County Galway).
The term Conamara is now commonly used (although incorrectly) to describe all of Galway west of Lough Corrib.
Conamara is often used to describe the Gaeltacht (Irish-speaking areas) of west Galway, however this is inaccurate as some of these areas are outside of the traditional boundary of Conamara.

Here, ice blocks several kilometers across, bearing the ubiquitous ridges characteristic of Europa, have broken off and floated; they seem to have twisted, tipped, and even foundered in a rough matrix, perhaps the once-again-frozen ocean that was temporarily exposed at Europa's surface.
One Pwyll ray is draped across part of the Conamara Chaos region.
Evidently Pwyll, which is the youngest of the large Europan craters and thus may have been formed roughly a million years ago, postdates much of Conamara Chaos.

Finally, the camera team has scheduled the processing and transmission of a picture of the Conamara Chaos region and another picture of a region of mottled terrain.
If some of these information sets sound familiar, it is because they are part of Galileo's normal period of re-processing and re-transmission of observations that have previously been transmitted to Earth.

Reconstructing the Conamara Chaos region helped convince him that ``the best, simplest and most obvious explanation is that there was melt-through'' from an ocean below the ice.
Greenberg suspects that portions of Europa's surface are resurfaced periodically by warm ocean water that melts through the thin ice sheet and bathes the surface.

It is thought that these lenticulae were formed by diapirs of warm ice rising up through the colder ice of the outer crust, much like magma chambers in the Earth's crust.
The smooth dark spots could be formed by meltwater released when the warm ice breaks the surface, and the rough, jumbled lenticulae (called regions of "chaos," for example the Conamara Chaos) appear to be formed from many small fragments of crust embedded in smooth dark surface like iceburgs in a frozen sea.
