My brief views of Sabah (North Borneo) suspected Impact craters. (Australasian impact craters?)
Note my GPS tracker (round blue) at Beluran, is in fact at Telupid township. Telupid 89320, Sabah, North Borneo.


This is a terrain imagery by Google maps on the State of North Borneo (Sabah) and even at this height there are four distinct asteroid impact craters explainable by simple physic.

Looking closely at the first three overlapping consecutive impacts, with extreme tensile force, has created a rift valley of about 50 Km long, 2 Km wide and has a depth of more than 100 meters and further west of the rift valley are terraces created by horizontally induced drag creating a transform boundaries.
Trajectory of all three came from the West with entry angle between 45° to 75° from ground zero. The first impact created the northernmost rim while the second impact overlapped the first and formed the now called Imbak canyon. The second impact crater is now called Inarad valley with its southern rim merging with the northern rim of Maliau crater, now called Maliau basin. The cratering of Maliau basin, measuring 25 km across is the most phenomenal impact, as the impactor strike a mountainous target with its flat surface slightly inclined upward towards East, flattening mountains, blowing outward part of the eastern rim of Inarad crater and further East of Maliau crater, its impact shock waves ejected a 8 km diameter mountain with a socket feature of a shattered cone pattern.

After the third impact, the eastern region was churned due to underground shock wave and vibration thus attaining fluidization condition, when the fourth asteroid impacted on an almost liquid state target 50 Km from centre to centre north east of the Maliau crater.

This super-impact transformed the ground into a complex impact structure with multi-ringed rims and a twin central rebound. The extreme tensile force exerted Eastward has snapped the ground and created a 30km long rift, faulting to more than 200 meters deep and 2 km wide west of the crater.
I would just name this structure as Deramakot complex crater. Further East of Deramakot is a probable transient crater forming weak ripples and central uplift, maybe the impactor is a break away from Deramakot impactor main body.
These areas was conserved and reserved by the state government as eco tourism spots and UNESCO program. However many strewn fields, ejecta curtain lies on privately owned lands and Forest reserves, this is where I rockhounds.
