The famousDelhi Ridgeis the last leg of the AravaliRange,
which traverses throughSouth
Delhiand terminates intoCentral DelhiwhereRaisina hillis its last extension. It is one of
the world's oldest mountain ranges. It dates back to a pre-Indian
subcontinental collision with the mainlandEurasian
Plate. The southern end is atPalanpurnearAhmedabad,Gujarat.

its lakes lies on the south slope of the range in Rajasthan. Numerous rivers

The AravaliRange
is the eroded stub of a range of ancient folded mountains. The range rose in aPrecambrianevent called the Aravali-Delhiorogen. The range joins two of the
ancient segments that make up the Indiancraton,
theMarwarsegment to the northwest of the range,
and theBundelkhandsegment to the southeast.Old fold mountains are characterized by
having stopped growing higher due to the cessation of upward thrust caused by
the stopping of movement of thetectonic
platesin theEarth's crust below them. In ancient
times they were extremely high but since have worn down almost completely by
millions of years of weathering. In contrast, theHimalayasare continuously rising young fold
mountains of today.
