It is limited to the south by the coast of the English Channel. The region is principally rural with major urban areas concentrated on the southern coast including Bournemouth, Poole, Southampton and Portsmouth with smaller market towns inland including Dorchester, Yeovil, Salisbury, Devizes, Winchester, Andover and Basingstoke. Figure 1 provides a geological sketch map of this region showing the rock types occurring in relation to the major towns and cities. Geologically the region forms the western part of a deep basin filled with sediments laid down in ancient seas. This account outlines the geology of the region to a depth of at least 1 km and summarises the current and historical use of the geological resources in the area.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;"></ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">The region is generally low-lying with ridges, rising up to 300 m.

The regularly-spaced boreholes provide valuable information about the geological layers at depth with more than 250 of these being over 150 m in depth and with a significant number reaching depths in the range 1500 to 3000 m. Geophysical seismic surveys provide information on the rocks between these boreholes by sending sound waves through the ground. Together these data provide a reasonably good understanding, to considerable depth, of the extent and variability of the rock units, and their structure. Understanding is improving all the time as a result of continued interest in oil and gas exploration, particularly in the south and west of the region. Concealed coal deposits are not known at depth within the region and consequently no deep mining has occurred.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;"></ins></div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>[[category:Regional Geology | 15]]</div></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>[[category:Regional Geology | 15]]</div></td></tr> <!-- diff cache key wiki_db-mw_:diff:1.41:old-6103:rev-6106:php=table --> </table>
