As a geologist with a keen interest in the interaction between the human body and extreme environmental conditions, I can provide an in-depth analysis of what happens when a human body comes into contact with lava.
Lava, being a molten rock, is an incredibly hot substance that can reach temperatures up to 1,200 degrees Celsius (2,200 degrees Fahrenheit). This extreme heat is capable of causing severe burns and tissue damage upon contact. However, the concept of "melting bones" is a bit of a misnomer. The human body, and specifically the bones, do not melt in the same way that ice or metal would when exposed to heat.
Bones are composed of a complex matrix of collagen and hydroxyapatite, a mineral that is quite resistant to heat. While the collagen can denature and break down at high temperatures, the hydroxyapatite does not melt. Instead, it would require a much higher temperature to undergo a phase change. The human body would be incinerated long before the bones reach a state where they would melt.
When a person falls into lava, the initial contact with the molten rock would cause immediate and severe burns. The skin and soft tissues would be vaporized almost instantly, and the heat would continue to penetrate deeper into the body. The intense heat would cause the body to undergo a process known as "spontaneous combustion," where the body's own flammable materials ignite and burn.
It is important to note that the lava's viscosity and flow rate also play a role in the interaction with a human body. Lava that is more fluid can envelop the body more quickly, leading to a faster and more complete combustion. On the other hand, more viscous lava might not engulf the body as rapidly, but the heat would still be sufficient to cause severe damage.
In the rare instances where a body has fallen into lava, the remains are typically not found in a recognizable form. The intense heat and combustion process would reduce the body to ashes and small fragments of bone. These remains are often scattered and may not be recoverable.
Furthermore, the lava's proximity to its freezing point is an interesting point to consider. While lava is indeed very close to its solidification point, it is still in a liquid state and can still cause catastrophic damage to the human body. The concept of "meat does not melt" is also incorrect in this context. The soft tissues of the body, which include muscle, fat, and other organic materials, would indeed be vaporized or burned away by the heat of the lava.
In conclusion, while the human body and bones do not "melt" in the traditional sense, the extreme heat of lava would cause rapid combustion and destruction of the body. The bones, composed of hydroxyapatite, would not melt but would be reduced to fragments by the intense heat. The rare instances of human bodies falling into lava result in complete incineration, with no recognizable remains.

In addition to the "bones don't melt" answers which can be supplemented with "meat does not melt", it is interesting to note what happens on the rare occasions that people have fallen into lava. The lava is very close to its freezing point as it oozes across the ground- it is basically just barely molten.
