Time for a guest blog from Mike Rumsey, to tell you all what the Mineralogists got up to on the days they split up from the Palaeontologists.

 

Having another geological commitment to attend I arrived in the middle of the night a couple of days after everyone else had settled into the Morrocco fieldtrip – a long taxi drive by darkness and a rough couple of hours sleep and then it was off into the field with the other mineralogists. (We split up so the palaeo people and the min people could get as much done as possible). First up was the amazing abandoned mining town of Angil, nestled in a steep valley once mined for its copper and lead content.

Although an incredible vista, the many hundreds of steps leading up to the top of the valley was difficult in the heat and having only had a few hours sleep – it was a real fieldtrip wake-up call! We found some representative material with our local guide and then moved onto the main important task for the day – Mibladen.

 

The Mibladen area is famous for beautiful bright red crystalline specimens of vanadinite, which are probably the best in the world, and as such Mibladen is well known to most mineralogists and it was great to visit such a famous locality. Vanadinite from here has been known for a long time, but most of the material that ends up in the UK is poorly located and is often just labelled vanadinite from Mibladen, Morocco - this is not really fit for some of the scientific purposes of the museum, so we wanted to collect material directly from a number of different outcrops, mines and workings so we could record exactly where subtly different specimens of vanadinite occurred.

Another feature of the material that reaches the UK on the commercial market is that it has often been heavily prepared. This might involve cleaning in acids or selective trimming or removal of other less aesthetic mineral species that get in the way of the bright red vanadinite crystals. This is unfortunate as we are losing geologically relevant information when this happens, so I wanted also to obtain some ugly, fresh material that might have all sorts of natural alterations, erosion crusts and associated minerals combined that could tell us or future geologists something a little extra about this place than the readily available specimens.

 

After a few hours of driving between localities and getting some quick representative samples the day was complete before I knew it, but I had lots of samples and was happy - we met some really interesting people and saw some incredible hand-dug mines and pits in the middle of the desert where prospectors had been searching for vanadinite.

 

On the second split day from the palaeo guys, we mineralogists visited the area of M’fis and Taouz, M’fis is a famous area for barite specimens and Taouz is another area famous for its vanadinite. Both these places were really out in the middle of the desert and it was very, (very!) hot - a specific locality called the wulfenite vein at M’fis – was so open and exposed, it felt a bit like some horror film where we might have been abandoned in a desert oven.

Still we got to it and collected some really interesting specimens from some more off the beaten track spots in M’fis including areas that have never really been written about or documented in any systematic fashion. At the main site of M’fis we picked up some good representative barite specimens and saw some pretty scary mining operations that I’m certain you would not see in the UK.

At Taouz we didn’t collect much as I had been lucky enough to visit the locality the previous year. However, we did get some nice specimens from the local miners and we got a quick tour inside the mine workings to see some of the vandinite in situ, both of which we documented to better illustrate the geological environment of the finds from my trip to Taouz the year before.

Analysis of the minerals is still ongoing, but it seems successful so far, with a few species being identified and/or documented for the first time at specific localities and in one case, possibly the first documented occurrence in Morocco… and perhaps the first even for the planet, which considering there are only 4800 known minerals is a fairly rare occurrence.

 

Huge thanks to Mike for writing this so I could share his experiences of Morocco!

Day three was the day I was most excited about. The Palaeontologists and the Mineralogists split up and went to separate places. You can read about what they got up to in the next blog, a guest post from Mike Rumsey. The Palaeontologists were heading to an area known as Goulmima. The reason we were heading there was primarily to explore the fish and ammonite fauna to be found (there are also marine reptiles). These animals are from the Turonian stage of the Late Cretaceous. This means that these fossils are approximately 90 million years old! Being the curator of the fossil cephalopods and a particular fan of ammonites I was very excited!


Before we left our hotel we visited the fossil and mineral shop they had to have a look and see what there was. There were some very impressive large items but I was most impressed by the heteromorphic ammonites and spiny trilobites.

We left our hotel and drove south, heading towards Goulmima. On the way we stopped in a town called Rich, where we visited another fossil shop. The owner of this particular shop knows the Goulmima area which we were interested in very well, he also had a lot of fossils from the sites there.  Knowing that we wouldn’t be spending very long at the site at Goulmima, and also that the Museum is working to expand its collection of ammonites from the region I spent some time having a look for the rarer species not represented in our collections. In the end we came away with some very nice ammonites.

After our detour we continued on the way to Goulmima. The drive there was filled with spectacular scenery as the landscape became more filled with the typical desert scenes you would expect from Morocco.  As we got closer we were driving along a river bed with spectacular cliffs and lush vegetation. On arriving we had lunch in the shade under a date tree (more fantastic tuna sandwiches!).  During our 300km drive south it had gotten noticeably hotter, I was definitely grateful for my sun hat and factor 50 suncream!

Once we had eaten our lunch we went to the first of two sites in the Goulmima area known as Asfla 1 (another town nearby). The more adventurous of the group scrambled up a very steep cliff to investigate what could be found. Lower down we found evidence of shell beds containing  lots of bivalve shells. After half an hour or so there we had found a few scrappy bits of ammonite and no fish so we got back into the jeeps and headed off to the second site; Asfla 2.

On reaching Asfla 2 we hopped out of the jeeps and headed up towards the site. On the way up we found pieces of plesiosaur. Martin found a lovely specimen of an ammonite genus known as Mammites at this site.

Our next stop before heading towards a place called Erfoud and our hotel was a small settlement near Goulmima. We were taken here by our guides as the local people make living excavating fossils from the area. We made a couple of stops, one of which being to a man who specialised in collecting the ammonite fauna. I spent another happy few minutes having a look through a pile of ammonites. In the end I came away with a good selection of specimens, some very rare which may never have been found here before!

The last stop before our hotel was a brief stop in another fossil shop. As we were now in Erfoud an area with much older Palaeozoic rocks, this was starting to be seen in what the shop was selling, with goniatites and trilobites which are much older alongside the more recent Cretaceous fauna.  While we were here Mike, Emma and Helena; the mineralogists met us so we could head to our hotel and a comfortable bed after a long and busy day.
