Objective

Together we want to explore the local geology from the earth's Moho, metamorphic rocks to the sedimentary cover. We will study in-situ depositions and the corresponding later rocks. Oman is known as the geologists paradise due to its wealth of geological processes and the lack of vegetation.

Safety, health

Oman is considered a very safe country, crime rate being very low.

Please ensure that you have your vaccination up to date, your health insurance covering possible expenses.

Please ensure that you have an insurance bringing you back to Germany in case of health issues. Check for example with ADAC Rückholversicherung, DRF membership or others.

Wadis may be wide and flooded quickly, even if it didn't rain. Such flash floods are a result of rain in the mountains, the water expelled through the wadis to the ocean.

Don't hike alone, have enough food and water and leave your route with somebody in case of emergency. Note that some regions are not covered with GSM / mobile phone.

Always have enough bottled drinking water with you.

incidents 2018 - the trip went fine and nothing unexpected happened:

  • three torn tyres, one car temporarily broken, 2hrs all digging our big truck out of the sand
  • we've seen scorpions, snakes and m-sized turtles
  • some dirrhoea, everyone realized quickly that sun protection and some liters of drinking waters per day are essential to feel well

Climate and nature

Temperatures are expected  30°C+ during the days. Take precautions of sun burn and heat stroke.

Driving is offroad and thus may be a bit "shaky".

We will be at sea level at the Gulf of Arabia and the Indian Ocean, and drive up to app 2000m.

Please note that flora and fauna are different. Plants may be poisonous. Poisonous snakes as well as scorpions are well known. Take special care at dawn and night.

Food

Food will be provided during the trip, but not on the arrival and departure day.

Cultural respect

Please respect the local cultural values. Short trousers, uncovered knees and shoulders show disrespect. Neither take pictures from people without their agreement, nor from local security facilities.

Don't touch or take away rocks from archeological sites, and don't take rocks of fossils from the exposures out of the country.

Do not pollute the water, especially not the the water of the Falaj system, which is the local drinking and irrigation water.

Do not take vegetables or fruits from the oases, and don't walk away from paths in oases.

Take your litter home.

How to join

Students interested to join are requested to put their name and contact details on a list at our secretary. Seats are limited, since we aim to keep costs low by having all seats taken in each 4WD.

In April the final list will be announced latest. Within a given deadline students are then requested to provide the flight booking confirmation and to make the payment for local costs.

Deliverables

You are requested to take notes and pictures, since it is unlikely that you will visit these places a second time. Together we want to make a movie from teams filming different scenes.

Personal Note

Having lived in the country with my family for a while, it really is a pleasing country with stunning scenery and very polite people. During that time and frequent trip to the mountains and desert, we just had one scorpion in our house and I heard a snakes hiss in a wadi at night once. In our home we had one gecko as guest, who took care of insects.

Oman is called the geologist's paradise, which is well reflected by many trip of hobby geologists and professionals to the region.

At night you will see the milky way and more stars than ever. However, an old French desert geologist and good friend of mine told me to always sleep in a tent at night, since we are unaware of pestering insects while you sleep.
