❓ If one day Africa splits into two parts and a new ocean forms, how will the world map change?
Scientists have just published the first geochemical evidence showing that a fault system deep under Zambia is active, possibly the beginning stage of continental separation in Africa.
The study focused on the Kafue Rift Zone in Zambia. In the hot springs, the team detected a high proportion of helium isotopes originating from the Earth's mantle, demonstrating that material from a depth of 40 to 160 km is moving closer to the surface. This is a very important sign that the shell is being stretched. 
IS THIS PROCESS DANGEROUS?
The answer is yes, but not for several years or decades.
Continental separation occurs extremely slowly, usually only a few millimeters to a few centimeters per year. If this process continues, tens of millions of years from now East Africa and part of Southern Africa could separate, creating a completely new ocean.
IMPORTANT SCIENTIFIC DATA
Parameter Value
The length of the fault system is about 2,500 km
Mantle connection depth 40 – 160 km
Main country of study Zambia
Signs of detection of helium isotopes from the mantle
The time it takes to form a new ocean is tens of millions of years
WHAT AREA IS CHANGING
This rift zone extends from Tanzania through Zambia to Namibia. This is an extension of the East African Rift system, one of the most active tectonic regions on the planet.
WHAT WILL HAPPEN IN THE FUTURE
As the Earth's crust continues to thin, magma can rise, causing more earthquakes, volcanoes and geothermal sources. In the long term, seawater could flood into the crack and create new oceans, similar to how the Red Sea was formed.
WHY IS THIS FINDING IMPORTANT?
Not only does it help understand the planet's evolution, this area also has great potential for:
• Geothermal energy
• Helium gas for medical and chip technology
