The phrase "accumulation threshold" is correct and usable in written English.
It can be used in contexts related to finance, data analysis, or environmental science, where a specific level of accumulation is significant for decision-making or analysis.
Example: "The project will only proceed once we reach the accumulation threshold of 1,000 units."
Alternatives: "cumulative limit" or "collection threshold."
Following Bonadonna (2006), we quantify the probability of hazardous thresholds of mass accumulations using: P[M x,y) geq M_{T} mid eruption] where M x,y) is the tephra mass accumulation (kg m−2) accumulated at given locations and M T a mass accumulation threshold.
Selecting the accumulation threshold value is largely subjective.
For further discussion of the impact of watershed accumulation threshold selection, we refer to Band (1993).
The buoyancy-driven hydrocarbon accumulation threshold is a new geological concept in relation to buoyancy-driven hydrocarbon accumulation (White 1885).
The dynamic boundary corresponding to the lower limit of hydrocarbon accumulation is regarded as the hydrocarbon accumulation threshold.
The accumulation threshold should be set to ensure that 'impassable' terrain is separated by the watershed boundaries.
Hayes et al. (2015) proposed tephra accumulation thresholds for when different clean-up responses and methods are initiated (Table 1).
Figure 55 shows the comparison of predicted buoyancy-driven oil accumulation thresholds with drilling results in the Putaohua reservoir in the Songliao Basin.
Tephra fall accumulation thresholds for clean-up actions are proposed by Hayes et al. (2015), the accumulation for Bariloche and Jacobacci compares relatively well with the predicted and actual clean-up actions (Figs. 2 and 18).
The equilibrium between the driving force for upward migration of hydrocarbon (P e) and capillary force in tight media (P c) and overlying static water pressure (P w) is the dynamic mechanism of buoyancy-driven hydrocarbon accumulation thresholds.
Therefore, it seems unlikely that sensory evidence alone is what drives the rate of accumulation to threshold.
