Content
The content of the article is not completely relevant to the topic of lava fields. There is an aside in the introductory section about the best way to photograph a lava field, which is not applicable to the introduction and distracts from the subject. The last paragraph, discussing the physical and numerical aspects of an ancient lava field, is also not presented clearly and initially difficult to understand. The information contained in the article is in date, and other Wikipedia pages are also linked for clearer understanding of the topic. Some missing information that could be added is the process of formation, notable scientists involved, physical and chemical properties, presence on other planetary bodies, and if there is any threat to human life or the environment. The only information currently in the article is a basic definition and important examples.

Tone
This article does a good job of presenting a neutral tone. There are not any biased claims towards a particular position, nor are there any overrepresented or underrepresented views.

Talk Page
The talk page is not very active. There was one discussion about changing the name of the article from "lava plain" to "lava field," which was approved. There was also some criticism about the lack of citations. This article is a stub, and it is not part of any WikiProjects.

Draft of Contributions
Lava fields are large, mostly flat areas of surface or subaquatic lava flows.

Morphology
The final morphology of a lava field can reveal properties such as internal structure, composition, and mechanics of the lava flow when it was fluid. The ridges and patterns on top of the lava field show the direction of the channels and the oftentimes active lava tubes that may be underneath the solidified "crust." It can also reveal whether the lava flow can be classified as pāhoehoe or 'a'ā. The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another.

An important aspect of lava flow morphology is a phenomenon known as lava flow inflation. This occurs in pāhoehoe flows that have a high effusion rate, and initially forms a thin crust atop the lava flow. The fluid lava underneath the crust continues to increase due to the sustained high effusion rate, and thus the entire "structure" increases in size, up to four meters in height. This anomaly can expose important physics and mechanisms behind lava flow that was not previously known.

The structure of lava fields also vary based on geographic location. For example, in subaqueous lava fields, sheet flow lava is found near volcanoes characterized by fast-flowing centers, like the Galapagos Rift, while on the other hand pillow lava fields are found near more slow-flowing centers, like the Mid-Atlantic Ridge.

Although the structure and composition of lava fields can reveal certain aspects of lava flow, there is currently little known about the reasons behind certain flow types, and it is also difficult to predict what sort of morphology a lava field will express before it takes place. Computer modelling is consistently increasing in quality, but the many micro factors directing lava flow and shape, such as source geometry and lava extrusion rate, limit the accuracy that is currently available.
