Date . . Chapter 1. 0AbstractThis is a study of the Massif Montgris, it is based on evidence gathered in thefield over 21 days of field work. To supplement this data I have looked atpapers and works by previous visitors to the Montgris.
The units within thearea are from the Upper Cretaceous the Tertiary and the Quaternary. I aim togive an overall guide to the geology on a smaller scale than has previously beenaccomplished. This study is mainly aimed at correctly dating the units oflimestone using micropalaeontological data. The micropalaeontological data hasalso given light into the palaeoenvironment/geography during deposition. Chapter 2Introduction2.Order now
0. 1 IntroductionBetween the 24th of June and the 24th of July 1995 Glen Burnham and I venturedto Catalunya. More precisely to Torroella de Montgris. Torroella is in theNorth East of Spain, just inland of the Mediterranean sea. This remarkable oldtown lies at the foot of the rather imposing Massif Montgris.
Locally known as “El Montgris” (literally the grey Mountain) the massif rises upover the town and dominates the skyline. Torroella sits on quaternaryconglomerate deposits. These are easily eroded, hence the valley between Pals(10Km to the south) and Torroella is extremely flat. The valley is bisected bythe river El Ter, which flows at a leisurely pace from the foothills of thePyrenees. The river flows to the south of Torroella and winds it’s way to itsconclusion in the Playa de Pals (6Km east of Torroella). El Montgris has been known to humans since prehistoric times.
It has some largecaves on its slopes that served as a shelter to prehistoric man. The area wasvery popular with the Romans who cultivated the local area, built roads andtowns (many of which still stand to this day) such as Peretelada to the southadjacent to Pals. Since the time of the Romans Torroella has grown into a thriving market town. It has always had close links with the Montgris which until recently stillserved a purpose as a shelter, not , however, against the elements but againstPirates and marauders from the sea. In fact, on top of the Muntanya SantaCatherina stands the remains of a thirteenth century castle (the last castleever built in Spain).
El Montgris has provided for the local commerce since it was first settled. The local people value the Mountains greatly and still use them today. The rockfrom which our dwelling was made was quarried from the mountain, the castle rockwas quarried on the mountain. 2.
0. 2 Aims of Study. When I first considered the Montgris as a project area I realised thatinformation would be sparse and that the project would be more complicated thana similar project in the U. K because the environment is so very different andresources would be a great deal more difficult to access (due to the languagebarrier). I also realised the project would probably be very different to theproposal.
Before Glen and I left England we attempted to research the Massif Montgristhrough the usual channels in order to get an idea of what we would be facing. The research lead to a few vague leads, we new the rock was sedimentary and mostlikely limestone. Having visited the area previously I could recall a littleabout the rocks but was certain of their sedimentary nature. Our first lead came from an unexpected source. My parents had vacationed in thearea and upon my request had asked locally about any information pertaining tothe Geology.
The result was that they brought back a research map that datedthe Massif as Cretaceous but suggested it was composed of 1 massive bed. Weloosely agreed our study areas and arranged our projects accordingly. The localguide books and map had supplied us with information about the palaeontology(macro fossils) which suggested the rock was full of bivalves, brachiopods,corals and belemnites. Before leaving we were unable to unearth much more information BUT seemingly atthe last minute we were able to make contact with Dr.
David Brusi from theUniversidad de Gerona(departament del geophysica) who reassured us that upon ourarrival in Spain he would brief us on geology of El Montgris.Therefore, with very little in the way of .
