What you see are bedding surfaces. They formed horizontally in a sedimentary lacustrine environment, the Kailash Formation.
This is a reconstruction of the paleoenvironment:
As Gimelist noted, the sedimentary layers formed above a magmatic body.
The question is why they reached an altitude of 8,000 meters and are still horizontal.
It is an extreme example of the principle of original horizontality, which gives the polarity of succession. The materials above are newer than those below because they were deposited horizontally. The tectonic uplift didn't change the original horizontal arrangement.
Just to add on this point from the comments:
But this mount is the only mouth with this kind of formation in local mountain range
First, the image on the mountain's Wikipedia page clearly shows that the surrounding mountains also have the horizontal layers.
The Wikipedia page also states that:
Mount Kailash appears to be a metasedimentary roof pendant supported by a massive granite base.
The source links for that information are broken. In any case, what this means in plain language is that Earth's surface had sedimentary layers, which are very common, and magma intruded underneath it. This is also very common. For example, the Andes and Cascades mountain ranges in Western South and North America are places where this is happening these days. Over time, the mountains (Himalayas) were pushed upwards by the Indian continent collision, and the rocks eroded away such that the mountain shows the top of the granite, overlain by the bottom of the sedimentary rocks like this:
