Although many models have been established in geoscience circles trying to analysis the Laramide orogeny,  there are still many unsatisfactory and suspect flaws left for debate since the critical element was neglected all the time.

It should be attributed to the XmoonAi (the predecessor of the Moon) that led to the dissembling of the unique supercontinent and coming into being of Laramide orogeny and the birth of Andes mountains by means of differential mutation at terminal cretaceous 66 Ma ago.

1.   the direct inducement of Laramide orogeny at terminal cretaceous.

Laramide orogeny refers to the formation of Rocky Mountains on western north American Plate at terminal cretaceous time.  Since Rocky Mountains were the north part of Cordillera mountains, the rest of it should be included in Laramide orogeny.  In other words, Laramide orogeny actually refers to the formation of whole Cordillera mountains at terminal cretaceous in a broad sense.

It is shown by Figure 1 as follows,

Figure 1:  The jigsaw recovery of the unique supercontinent at terminal cretaceous 66 Ma ago.

It was the sinking to the ocean floor of the ancient Jiazhou plate (the largest ancient plate) in the middle of the unique supercontinent^[1] on the equatorial area at terminal cretaceous 66 Ma ago that forced the mantle magma and even the colorful semisolid substances in the deep layers of mantle to spray out into the air and piled on the western edge of new born ancient American plate (including the new born ancient Jingzhou plate, the predecessor of ancient Antarctic plate ) and evolved to be the added terrenes^[2] of Cordillera mountains,  following the dissembled of the unique supercontinent and rotating anticlockwise and drifting northwards of the ancient plate group (excluding the ancient Jingzhou plate) at a speed of as slow as that of a snail moves in the past 66 Ma.

Therefore, the birth of the Cordillera mountains was the same as that of a flash in some degree by the pattern of differential mutation.  However, the new born Cordillera added terranes were scoured fiercely by the megaflood melted from the shell clothes of snow and ice of the XmoonAi.  While the dinosaur family turned out to be the unfortunate sacrifice of extinction with some of it buried suddenly to be the fossils by the Cordillera added terranes.   It is shown by Figure 2 as follows,

Figure 2:   The Cordillera mountains were born by pattern of differential mutation 66 Ma ago.

2. The indirect inducement of Laramide orogeny at terminal cretaceous.

It was the XmoonAi (the predecessor of the Moon) who contributed a slight kissing on the ancient Jiazhou plate of the unique supercontinent 66 Ma ago in the direction from west to east that led it to sink to the ocean floor.   Therefore,  the indirect inducement of formation of Cordillera mountains was the celestial body love event happened between the XmoonAi and the unique supercontinent of the Earth at terminal cretaceous 66 Ma ago.  It is shown by Figure 3 as follows,

Figure 3:   The indirect inducement of Laramide orogeny at terminal cretaceous.

3. the causes analysis of the outline difference between north and south Cordillera mountains (Rocky and Andes mountains).

It is well known that as the added terranes born of the same time, the outline of Rocky mountains looks wider but lower (fatter),  while the counterpart of Andes mountains looks narrower but higher (thinner).

The causes for their differences should be attributed to the kissing direction of the XmoonAi on the ancient Jiazhou plate and the birth direction of western edge of the ancient north and south American plates 66 Ma ago.

The western edge of ancient north American plate was born almost parallel to longitude that perpendicular to the moving direction of the XmoonAi (from west to east),  while the counterpart of ancient south American plate was born almost parallel to latitude line that parallel to the moving direction of the XmoonAi.  Therefore,  it is reasonable to deduce that mantle substances spraying out of the edge of ancient north American plate were impacted fiercer than that spraying out of the edge of ancient south American plate under the impact wave of kissing point of the XmoonAi at the terminal cretaceous 66 Ma ago.  Thus, the interesting and more contradiction of the outlines came into being on the Earth between the north and south Cordillera mountains (Rocky and Andes mountains) in the past 66 Ma.  What’s more,  it led to the existence of fold and thrust belt in large quantities in the Cordillera mountains by the impact wave of kissing event between the XmoonAi and the ancient Jiazhou plate 66 Ma ago.   It is shown by Figure 4 as follows,

Figure 4:   The impact wave direction of the kissing point on the ancient Jiazhou plate (X1) triggered by the XmoonAi at terminal cretaceous.

4. the previous stage of indirect inducement of Laramide orogeny at terminal cretaceous.

The previous stage of indirect inducement of Laramide orogeny at terminal cretaceous was once the collision between the Milky Way galaxy and the Xplus dwarf galaxy from which the XmoonAi (the predecessor of the Moon) originated.

It has been observed and deduced by the astronomists that the Milky Way galaxy had been a mix-blood galaxy and expanding itself by colliding with and swallowing other dwarf galaxies in the past tens of billions of years.  It is shown by Figure 5 as follows,

Figure 5:   The previous stage of indirect inducement of Laramide orogeny at terminal cretaceous.

5. the celestial body language implied by the colorful Cordillera mountains.

It is implied by the colorful Cordillera mountains that it was the fascinating and attractive kissing lip print^[3] left by the celestial body love event happened between the XmoonAi (the predecessor of the Moon) and the Earth at terminal cretaceous 66 Ma ago.   It is shown by Figure 6 as follows,

Discussion

1.  Was the Laramide orogeny related to the hypothetic models of oceanic plateau subduction or oceanic islands collision that popularized in geoscience circle?

Laramide orogeny had nothing to do with oceanic plateau subduction^[4,5] or oceanic islands collision since that kind of model was processes of much slower evolving and could not explain the phenomena of fold and thrust belts and dinosaur fossils buried in Cordillera mountains in large quantities and dinosaur extinction suddenly at terminal cretaceous 66 Ma ago.   It is well known that dinosaur fossils would come into being mostly by the living dinosaurs were buried suddenly by mantle substances in an extremely short time the same case as the human fossils came into being in the Italian Pompeii by the human beings were buried suddenly by the eruption of Vesuvius^[6] volcano in AD 79.   It is shown by Figure 7 as follows,
